Competitive Edge

Whether you are developing a new product or looking to extend the life of an existing product, one of the key necessities is that it should offer real benefits over your competitors. When we look at products that incorporate an optical system a competitive edge could be as simple as providing higher resolution. However, with the increasing pace of technological development today just how long will that competitive edge last?

To achieve a competitive edge that lasts you need that your product incorporates a unique component to provide advantages and improvements that your competitors do not have access to. One well proven route to achieving this with cameras, sensors and optical instruments is that your product should include a performance optimised custom lens or lens system designed specifically for your application. Such optimised custom lenses provide you with the desired competitive edge. Most important is that your optimised custom lens has been developed on an exclusive basis, placing a considerable hurdle for your competitors to overcome in order to compete with you.

There are many ways in which an optical system can provide competitive edge:

Size - An increasing number of applications are constricted by a lack of space in which the optical measurement device can sit. Keeping lens designs compact is a speciality of Resolve Optics.

Format - Sensors are evolving constantly and there seems to be a trend towards moving away from standard formats. Having a custom lens optimised to leverage top performance from non-standard format sensor can give you an advantage.

Resolution - All industries are information hungry and consequently are pushing for higher and higher resolution. Achieving highest possible resolution is rarely done with a standard off-the-shelf lens.

Aperture - Lens performance is affected by how much light you can get through it i.e. its F-number. Specialist lens design helps you achieve the maximum F-number in the application space constraints.

Wavelength - Most applications have a key bandwidth or wavelength at which optical measurement / sensing is optimally carried out. Designing a lens / lens system to provide peak performance in the key bandwidth / wavelength can give your product an edge.

Mechanical interface - Some applications and operating environments place great demands on an optical system. Consequently having a custom lens mounting arrangement, for instance to minimise the detrimental effect of vibration, can place your product head and shoulders above the competition.

A custom lens with a single one of these advantages can definitely give you a competitive edge. However if your product incorporates a custom lens that offers several of the above optimised performance factors it is then possible to achieve even greater competitive edge.

Such performance optimised products typically take a larger share of the available market demand and consequently are a benefit to your company's bottom line. In addition having an exclusively developed optimised custom lens in your product gives you the benefit of security of supply. Standard off-the-shelf lens unfortunately are only available for as long as the market is sufficiently large to justify their existence. As just one of many purchasers of a particular standard off-the-shelf lens you are unlikely to be able to influence the manufacturer supplying such a lens.

To discuss development of a custom optimised lens to give your new product a competitive edge or extend the sales life of a core product please contact Resolve Optics.

Setting Up a Tracking Zoom Lens for Optimum Performance

The term "tracking zoom”" is used to describe a zoom lens that, once set-up, will maintain focus throughout the full zoom range of the lens. For example all Resolve Optics Ltd zoom lenses are tracking zooms.

Tracking zoom lenses are of great benefit to users. However, to get the best performance from your lens you must set it up correctly each time you use it on a new camera. If you only use the lens on a single camera then the set-up need only be performed once. However, it is recommended that you periodically check the set-up to make sure nothing has changed and best performance is maintained.

Setting-up your tracking zoom is a relatively simple procedure but absolutely vital to ensure the best performance from your zoom lens.

Step 1. With the Zoom Lens mounted on the camera, zoom to the narrow image and use the lens focus to bring the image into sharp focus.

Step 2. Now zoom to the wide image. The image is likely to be out of focus consequently you need to focus by adjusting the register or back-focus setting. This can be done by using the lens register setting (if provided) or the camera adjustment. By adjusting the register you will bring the image back into best focus.

Step 3. Repeat steps 1 & 2 several times until focus is maintained at either end of the zoom without having to refocus. You will now find that optimum image quality is maintained at any point within the zoom range.

Your Zoom Lens is now set for optimum performance. Please keep in mind that this set-up procedure should be carried out even if you are swapping the lens between cameras with the same standard lens mount. Tiny positional errors between the camera register and sensor position can be enough to stop your lens tracking correctly.

Technology Forum 1

Sensor Resolution versus Lens Resolution

An informative new white paper from Resolve Optics addresses the often misunderstood considerations when selecting an optimum lens for your digital camera or sensor. The ability of a lens to resolve detail is usually determined by its quality but also is ultimately limited by diffraction. It is commonly thought that the resolution of a lens should match or exceed the Nyquist resolution of the sensor that it has been selected to work with, in order to achieve optimum performance. This is a common misconception.

Are Off-the-Shelf Optics Always the Best Solution?

A white paper from Resolve Optics addresses the commonly asked question 'Are off-the-shelf optics always the best solution ?'. Today there exists a huge number of off-the-shelf lenses for mass market applications where unit cost is the dominant driving force. However when it comes to an application that optically requires anything a little more demanding such as high performance, high-resolution, compactness or a large image format then adopting an off-the-shelf lens typically will force you to accept a compromise in one or more aspects of optical performance.

Product Focus 1

Wide Angle Adapter for 3CCD HD Cameras

The Model 387 has been developed to provide a cost effective route to achieving a wide field-of-view for HD Broadcast applications with no loss of performance. The Model 387 converts the 4 mm focal length Fujinon TF4XA-1 HD lens to a 2.8 mm focal length while maintaining its high definition 200 cycle performance across all the sensors of 1/3-inch 3-CCD or 3-CMOS cameras. In doing this the Model 387 usefully increases the horizontal field-of-view from 71 degrees to a minimum of 95 degrees.

Dimensions of the Model 387 are 60.5 mm diameter and 34 mm long. The adapter mounts onto the TF4XA-1 via the 30.5 mm external thread on the front of the lens. The Model 387 wide angle adapter has an M60 x0.5 thread on the front to facilitate the mounting of filters.

For further information on the Model 387 please visit www.resolveoptics.com/387-000-0-7x-wide-angle-adapter/

Product Focus 2

Close-Up Inspection in High Radiation Environments

Designed to provide uncompromised performance on 2/3-inch cameras, Resolve Optics new 6mm focal length Model 214 and 9mm focal length Model 286 lenses deliver high image resolution (f2) and minimal geometric distortion from 400 - 750 nm. Manufactured to the highest quality standards from Cerium doped glass, Model 214 and 286 lenses are able to withstand radiation exposure of up to 100 kGy (100,000,000 rads) and temperatures up to 55 degrees centigrade without discoloration. Most non-browning glass lenses are yellow tinted which unfortunately gives images acquired by colour CMOS cameras a yellow appearance. To provide a solution for this problem, Resolve Optics has introduced the Model 313 - a 25mm focal length (f1.4) fixed focus non-browning lens. Using specially selected glasses with the least amount of yellow tint, so that the image would be as natural as possible, the Model 313 still retains non-browning performance in environments subject to radiation.
