Optics Assemblies

375 to >2000 nm; 0.59 to 1.3 inch Diameter Flange; Compact Housing; Low Losses; Custom Design for User-specified Diodes Available OZ Optics' HULDO laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. It consists of a laser diode holder, a collimating lens holder, and a high numerical aperture (NA) collimating lens. By adjusting the distance between the laser diode and the collimating lens, the laser diode output can be collimated. Laser diode collimators are available in different diameters. The standard diameter package is 0.79 inches in diameter, fitting most diode types. A larger, 1.3 inch diameter housing is used for larger diameter diodes such as H1 or TO-3 packages. For diode can sizes of 9.0 mm or smaller in diameter a 0.59 inch diameter housing is available. Smaller housings with 10 mm OD's are available for OEM applications.We also offer special compact laser diode to fiber couplers for OEM applications. These packages have the diode and collimating lens permanently glued into the same housing. This package features a compact, rugged housing, at a significant reduction in cost. Choose from our selection of laser diodes, we can also supply you with laser diode power supplies (operating from battery or DC voltage source). We can even provide you with complete miniaturized packaged systems. Contact us for more information on what is available.

Effective Focal Length EFL 3.2-19.0 mm; f/# 1.0, 1.1; FOV 13.9°x10.4°-50°x37°; Recommended Detector Resolution 160x120-384x288 Pixel; Recommended Detector Pixel Size 12, 17 µm; Working Distance 3.07-12.0 mm For immediate use in thermal imaging cameras, GH Optics' infrared precision molded aspheric lenses are available pre-assembled in aluminium/plastic housings with a range of thread sizes. By using precision molded aspherics, this series of thermal imaging lens assemblies offers a cost advantage, especially in larger quantities. The assemblies are optically athermalized in a temperature range from -45°C to +85°C and available with different coatings, such as anti-reflection (AR), high-density (HD) or short wave blocking (SWB). Typical applications for these infrared thermal imaging lens assemblies are thermography, security & surveillance and diagnostics. Within our series of thermal imaging lens assemblies you find seven standard models, each one optimized for a certain detector size:   Lens Assembly Code Effective Focal Length (EFL) F# Field of View (FOV) Sensor Size Sensor Pixel Size Datasheet X61201 2.0 mm 1.0 90°(H) x 66°(V) 256 x 192 px 12 µm Datasheet X61321 3.2 mm 1.1 50°(H) x 37°(V) 160 x 120 px 17 µm Datasheet X61361 3.6 mm 1.1 50°(H) x 37°(V) 256 x 192 px 12 µm Datasheet X62361 3.6 mm 1.0 50°(H) x 37°(V) 256 x 192 px 12 µm Datasheet X61971 9.7 mm 1.0 27°(H) x 20°(V) 384 x 288 px 12 µm Datasheet X61A51 15.0 mm 1.0 25°(H) x 19°(V) 384 x 288 px 17 µm Datasheet X61A91 19.0 mm 1.0 13.9°(H) x 10.4°(V) 256 x 192 px 12 µm Datasheet If you don’t see the thermal imaging lens assembly you need in this list, we can have it custom built for you.
