OPTICAL COATINGS

1.      Antireflective hard coating for various glass and crystal.

Varieties of substrate: LiNbO₃, CaCO_3, KDP,KD*P,LiIO₃ YLF,YAG,YVO4,

KTP,BBO ,LBO,QUARTZ, BK7, Fused silica.

   Typical specification: R<0.2% per surface at 1064 nm or 532 nm etc.

2.      Broadband antireflective coatings

R< 0.5% at 420-750 nm per surface (average)

3.      Antireflective coating at 1064 nm + AR 808 nm

R< 0.25% per surface

4.      Reflectors for laser lines

R= 20% +/- 2% , 30% +/- 2%,40% +/- 2%,50% +/- 2%,70% +/- 2%,80% +/- 2% etc. At 532 nm, 632.8 nm, 694.3 nm. 1064 nm, 1300 nm,1550 nm etc.

5.      8~12 micron highly efficient broadband multiplayer antireflective coating

Transmission: (T)>95% (average) 8- 12 MICRON.

6.      Narrow Infra -red interference filter ( 3 ¨C 5 ) um.

7.      Long wavelength or short wavelength pass filter.

8.      Diamond like antireflection coating on surfaces of Ge, Si. Used for the surfaces of IR optical sysytem (waer ¨C proof) hardness near to that of diamond. Transmission is better than 95% at 3-5 um or 8-12 um
