Jwalin Laser Technology

We provides solid state laser users with a comprehensive range of glass filters. Depending on application, wide, narrow, long & short wavelength pass filters are available. For laser safety a range of attenuation (blocking) filter are supplied in a range of sizes.

All Focus Lens are available in a range of wavelengths; 355nm, 405nm, 532/633/780/830nm and 1064nm.

Beam bending mirrors are used to direct laser beams within an optics chain. A 45 degree angle of incidence is the most common bend. Most beam delivering mirrors are coated with both transmissive and anti-reflective coatings depending on application.

We provides a comprehensive range of retrofit beam bending and dichroic mirrors for many existing laser systems in the field.

Solid state lasers require mirrors maintaining lasing action. Most resonators consist of a high reflector (rear mirror) and partially transmissive output coupler (front mirror). Mirror substrates are produced from a range of high quality optical materials such as BK7, fused Quartz and other exotic glasses selected for its intended application. Laser mirrors are fabricated in a multitude of configurations such as convex, concave, flat, wedged or a mixture of both. Coatings are selected according to both maximum power damage threshold and wavelength criteria.
