Laser Quality or Normal Quality

LASER COMPONENTS uses mostly N-BK7 and fused silica (Q1, C7980) for its high quality lenses and plano substrates in laser applications, although special glass such as sapphire or flint glass is also available.

For LASER COMPONENTS "laser quality" refers to a surface figure of l/10 and a polish of the highest grade (N-BK7 and fused silica). If such high quality is deemed unnecessary, "normal quality" lenses and protective glasses (B270 and borofloat) are available at a lower cost. For both quality levels plano convex, plano concave, biconvex, and biconcave lenses are available.

The table shows the various levels of quality; each optic has a diameter of 1.0". The same goes for polarizers, beam splitters, and other optical elements.

In-house coatings can be applied to all optics. With twenty years of experience in in-house production LASER COMPONENTS can guarantee the best quality with the highest damage thresholds. Hard dielectric coatings are offered in the wavelength range from 193 nm to 5000 nm. When applying anti-reflection coatings to lenses, the customer has the choice between U-AR and V-AR for a remaining reflectivity of either R < 0.1% or R < 0.2%, respectively. The wide-band BBAR coatings have a remaining reflectivity of R < 0.4% and cover a larger wavelength range.

Quick delivery times play a decisive role, which is why a wide selection of substrates with and without coatings are in stock and available immediately.
