Crystal Optics & Photonics

Crystal Optics & Photonics extends the catalogue from chemicals into the components that guide and shape light. It covers optical lenses and prisms, windows and coated substrates, and laser crystals, mirrors, filters and wave plates. Examples include Barium fluoride windows in several diameters, Cerium-doped YAG single crystals, broadband non-polarising cube beam splitters, 532 nm band-pass filters and C-mount bi-telecentric lenses.

Choosing an optic starts with wavelength range. Barium fluoride and calcium fluoride transmit from the UV into the mid-infrared, while fused silica covers UV to near-IR. Then come dimensions, surface quality, flatness and coatings. For laser use, the damage threshold of the coating and substrate is critical.

• Lenses and prisms for imaging and beam shaping
• Windows and substrates in fluoride, oxide and glass materials
• Mirrors, filters and scintillator crystals for lasers and detectors

Optics are packed in protective cases with lens tissue and foam, then boxed to prevent knocks in transit. Custom sizes and coatings can be quoted on request.
