Customers engage Syntec Optics to conduct optical design development of LWIR lenses. An example is a request for the following specification: 25 mm EFL, f/1 and a FOV. The camera chip size is 640x512 with...

Customers engage Syntec Optics to conduct diffractive designs. Once the suitable material is determined, the first step of the design investigation is to design a single element. The design is optimized at a single wavelength and...

Syntec develops many designs during its investigation process after the camera applications are reviewed. Material selection is key, germanium (Ge), which has almost twice the index of refraction compared to ZnS (i.e. 4 to 2.2). The two element Ge...

Many commercial LWIR lenses are currently two element solutions. Diamond turning is a main component of the manufacturing requirements, although AR coatings are also a critical part of the process. ...

Precision molding of lenses using Chalcogenide glass affords considerably less expensive production cost in large quantities compared to SPDT (single point diamond turning) and a definitive and competitive price-performance ratio. Chalcogenide glass has attractive optical properties...
