Thin Film Engineering
The thin film deposition laboratory is a state-of-the-art facility specializing in infrared thin films for high efficiency anti-reflection coatings, bandpass filters, and high-vacuum metalized dewar windows. Unique and customized designs, such as the filter wheel to the right, are always welcome. With over 30 years of experience in thin film deposition, the product capability is second to none.



Mechanical Engineering

The mechanical engineering staff lays out every lens and system using solid modeling software, producing precision-scale drawings. This accuracy is not only necessary for the construction of a quality product, but also to ensure that it fits the customer's needs exactly. These three-dimensional textured models, such as the one below, help eliminate design flaws and conflicts before costly prototype and production work is performed. This model can also be worked up in plastic and foam so it can be held and visualized in real life.

 

Optical Engineering
The optical engineering staff utilizes the latest optical design software. This, combined with product development experience, results in efficient thermal infrared lens configurations. These configurations afford optical performance which meets and exceeds the requirements of our end users. This capability allows the Optical Engineers to integrate their designs with the diamond turning aspheric manufacturing, producing minimum element count designs. From simple objectives to complex zoom lens assemblies, the solution easily becomes a manufacturing reality.

Custom design and build to specification products are available.

 

3-5m Lens Systems

This selection of lens assemblies offers enhancements which permit the user to interchange lens assemblies by a simple twist and click. Most of these assemblies are fitted with the BAYONET MOUNT SYSTEM, which is common to the more popular 3-5m infrared camera systems. As with all the lens products, each unit is tested to meet a specific set of specifications. These lens systems are tested for the following parameters: effective focal length, back-working distance, MTF, transmission verification, and physical conformity.

8-12m Lens Systems

This selection of 8-12m high speed lens assemblies are designed for uncooled focal plane array thermal applications and offer enhancements which permit the user to interchange lens assemblies by a simple twist and click. Most of these assemblies are fitted with the BAYONET MOUNT SYSTEM (22605 series), which is common to many uncooled 8-12m infrared camera systems. As with all the lens products, each unit is tested to meet a specific set of specifications. These lenses are tested for parameters including image quality, transmission verification, and physical conformity.

8-12m, Cooled Lens Systems
(exterior exit pupil)

This selection of 8-12m lens assemblies are designed for long wave cooled focal plane array systems (i.e. QWIP or MCT) that require the exit pupil of the lens to be placed at the cold stop location in the dewar. Most of these lens assemblies are fitted with the BAYONET MOUNT SYSTEM (22188 series), which is common to many cooled 8-12m infrared camera systems. As with all the thermal infrared lens products, each unit is tested to meet a specific set of specifications. These lenses are tested for parameters including effective focal length, back working distance, MTF, transmission verification, and physical conformity.

Electronics and System Design

Electronics

Embedded systems have been developed for remote control of lens functions, blackbodies, and dynamic motion systems. Smart Lens Controls have been fielded all over the world in the Multi-Field of View lens products, being unique in their remote operation capabilities. If you require remote control capability, we have the solution.

Software

Existing software can be modified by our Software Engineers to meet specific needs. The array of software ranges from basic instructions that control FOVs to in-depth higher-level language programs on embedded processors to control imaging, precision focus and zoom, gain, I/O, and error correction.
