Our spherical plano-concave germanium lenses are largely used to diverge a beam from the collimated light source, or to improve the focal length of an optical process.
5µm. This leaves germanium as the top and only choice for brutally difficult IR applications. This is usually why you will see germanium windows and lenses serving in destinations as inhospitable as outer Room, battlefields and in the middle of higher-run CO2 laser devices. Far more on this later on.

Frequently, DLC coatings in many cases are paired with Broadband AR Coatings (BBAR) to not only up the more info mechanical efficiency but in addition the transmission Qualities. Typically, a window is coated on a single side with DLC and the other aspect with BBAR (normally within the seven-fourteenμm variety to spice up the two of such Houses in tandem.
We also recycle evaporation grade products from coating facilities. Novotech can be acquiring several semiconductor substrates and parts, which we've been converting back into their first features.
We can make customized requirements to non-regular sizes of optical crystals. Novotech can offer the fabric fabricated to most purchaser’s specs. With an in depth fabrication ability, we could generate typical generated lens blanks in a one particular-to two-7 days time frame.
