OYSTER BAY, N.Y., May 3, 2010 — Universe Kogaku America has expanded its line of quartz lenses with the introduction of the UV0928CM 9-mm ultraviolet f/2.8 lens for imaging applications in the nonvisible light spectrum. It is supplied with a C-mount but can be configured to suit any requirement. Available from stock in a wide range of focal lengths, the lens has a focus lock and is suited to forensic, industrial, scientific and other imaging applications. Because of the broad transmission range of the quartz elements, the lens also can transmit well into the infrared spectrum. Back focal length is 11.075 mm, image size is 3.6 × 4.8 mm, distortion is -5.6%, and vertical, horizontal and diagonal angles of view are 23.1°, 30.9° and 38.9°, respectively. Center resolution is 100 line pairs per millimeter, and corner resolution is 40 line pairs per millimeter. All surfaces are antireflection-coated.
