MOK Optics produces UV & IR fused silica with different dimension and shapes. The materials include Corning 7980, JGS1, JGS3 etc.
Laser optics play a crucial role in various applications by controlling and manipulating laser beams with precision. These optical components are specifically designed to handle the unique characteristics of laser light, such as its coherence, monochromaticity, and high intensity.
Sapphire window is a kind of excellent multifunctional material. It has high surface hardness, high temperature resistance, good thermal conductivity, UV-IR transmittance and good chemical stability. MOK Optics provide sapphire windows with various of dimensions and shapes, AR coating is available
The Germanium window, featuring AR coating and DLC coating, offers superior durability and high-performance infrared transmission, ideal for demanding optical applications.
CaF2 is transparent from the UV to the IR (180 nm – 8.0 µm). and is mechanically and environmentally stable.MOK Optics provides excimer grade CaF2, vacuum VUV grade CaF2, UV grade CaF2, IR polycrystal CaF2.
MgF2 is a synthetic crystalline substrate, transparent over a wide range of wavelengths (120 nm – 6.0 µm), magnesium fluoride is well suited for applications ranging from the UV to the IR. MOK Optics provides UV grade MgF2 windows, Max Diameter 170mm, Oriention:<001>,<100>,<110>.
Silicon (Si) is one of the hardest minerals and optical materials available for use in the NIR (1µm) to about 6µm. Optical quality Silicon is usually doped (5 to 40 ohm cm) to prevent absorption bands within the transmission waveband. Silicon has a lower refractive index than germanium and has a lower density that makes for less weighty optical designs.
Special sizes, shapes and materials are available upon requirement.
