Features

Laser Bars

OSRAM Opto Semiconductors (Santa Clara, CA) offers laser bars with a wavelength of 910 to 980 nm that achieve an optical output of 120W under real-world conditions and a typical efficiency of 70%. The laser bars have a 50% fill factor (the ratio of active width to overall width) and they are ideal for pumping solid-state lasers and direct material processing. OSRAM also plans to produce laser bars with wavelengths of 808 nm and 880 nm, which will deliver an efficiency of 62% at 120W. Structures with a fill factor of 20% are also available and are ideal for optical fiber coupling applications.

Remote Head Camera

Toshiba Imaging Systems Division (Irvine, CA) introduces the remote head IK-TF7H7U camera. The progressive scan model delivers true color video output of 1024 × 768 pixels at 30 frames per second at full frame and up to 90 frames per second in partial scan mode. The camera features 1/100 to 1/100,000 second electronic shuttering capability. The C-mount camera has a digital CameraLink® output for compatible interface with many standard frame grabber boards. The IK-TF7H7U weighs 65g and measures 32.6 mm × 38.6 mm × 41 mm. Two optional cable lengths of 3 and 5 meters are available. The camera is ideal for semiconductor inspection, machine vision, and other remote inspection and analysis tasks.

Fabry-Perot Etalons

Optical Surfaces Ltd. (Surrey, UK) offers Fabry-Perot etalons in a range of shapes and sizes up to 150 mm in diameter with matching accuracies to lambda/300. Etalons are used in telecommunications, lasers, and spectroscopic applications to measure the wavelength of light. Optical Surfaces Ltd. manufactures Fabry-Perot etalons in two basic forms: air-spaced or solid. Both types can be designed for use at customer-defined wavelengths within the range 190nm to about 2 microns. The Fabry-Perot etalons are available in materials including UV grade Silica and Germanium.

Optical Design Software

Optical Research Associates (Pasadena, CA) introduces CODE V® 9.81 optical design software with aspheric lens tolerancing capabilities that are valuable in the fabrication of optical elements. The Fabrication Data analysis feature provides a way to visualize interferogram data on a lens surface, entrance pupil, or exit pupil, including the ability to see rotation and scaling effects. Functions have been added to the Partial Coherence analysis and TOR tolerancing features, which provide direct information about the critical dimension of the image, assuming a one-dimensional, partially coherent image, which is the standard design metric for microlithography.
