Photonics Suppliers

CASTECH is a global leader in nonlinear optical crystals, laser crystals, precision optics, and laser components for laser applications, optical communications, biomedical VR/AR, and lidar. With ISO 9001 and IAFT 16949 quality management system, we consistently enable our customers from prototype to mass production stage.

Importer and distributor of photonics components and subsystems for use in instrumentation. Products include photomultiplier tubes, solid-state photodetectors, IR detectors, image sensors, scientific cameras, light sources, and x-ray solutions.

As a matured and professional global supplier with a sophisticated engineering background, we specialize in the manufacturing and sales of electro-optics, including laser crystals and components, laser mirrors, nonlinear crystals, wave plates, polarizers, optical windows and lenses, IR camera lens assemblies/optical filters, scintillators, and more.

Manufactures a wide range of IR sources or lamps primarily for the OEM market. Products include pulsable sources utilizing tungsten and Nichrome (NiCr) and steady-state sources utilizing Kanthal and NiCr filaments. All are constructed in industry standard TO-39, TO-8, and TO-3 size packages with gold-plated parabolic reflectors.

Provides customized materials for low stress, high purity, and high uniformity infrared crystals to customers in over 60 countries and regions around the world.

Standard and custom photodetectors and high-quality VIS and IR LEDs. Our advanced performance sensors operate from the extreme ultraviolet (UV) to the mid-infrared (mid-IR). Photodetectors provide high-energy particle, electron, x-ray, and UV detection; plus excellent mid-IR sensitivity to discriminate gases, detect heat, sparks, and flames.

Supplier of sophisticated materials for research or production applications. Offers laser crystals and laser components, optical components, optoelectronic components, metals (high purity or single crystals), plasma technology, UHV components, and precision wire saws.

Designs and manufactures IR detectors for the 0.5 to 24 micron range. Products include InGaAs, Ext-InGaAs, InAs, InSb, PC&PV HgCdTe detectors, linear and 2D arrays with a wide range of detector cooling options for defense, security/safety, chemical and biological detection, semiconductor inspection, life science, and spectroscopy markets.
