Knight Optical Introduces New range of Sapphire Cylindrical Lenses

Knight Optical can offer you Custom Sapphire Cylindrical Lenses, for use within Endoscopes.

Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5μm. Making it ideal as a protective window for camera systems.

Cylindrical lenses are designed to focus light into a straight line, rather than to a single point. As the name suggests, the lens surface has a cylindrical shape rather than the usual spherical which allows for one dimensional shaping of light along a line. Cylindrical lenses are often used to change the profile of laser beams, for example to correct for astigmatism and ellipticity in diode lasers or to generate lines from single mode lasers.

Typical specs:
Material:
Sapphire
Diameter Tolerance: 0/-0.25mm
Centration: 0.25mm (F.L < 50mm) 5mrad (F.L > 50mm)
Focal Length (@587mm): ± 2.0%
Surface Quality: <60-40 Scratch/Dig
Coatings: Coatings available

All our Sapphire Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
