Request InfoPOG Precision Optics Gera GmbHPräzisionsoptik Gera GmbH has developed wide-field collimator optics for in-line inspection of mobile phone cameras. The system can be integrated into production lines or used in stand-alone test setups. It is suitable for testing distortion, resolution and focus for a variety of objective lenses with a focal length of ∼4 mm. The collimator is adjusted to infinity and covers an object field of 68°. The standard reticle uses a chessboard pattern, which can be adjusted per customer request. Adjustable white-light LED illumination operating from a 12- to 24-VDC supply is integrated.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/13/2024Infrared PolarizersCoherent’s family of mid- and long-wavelength infrared wire-grid polarizers were made for use in applications such as laser based metrology and atmospheric remote sensing.
