TO ORDER : Specify part nmber as follows : Substrate Code + Radius Code + Coating Code

Plano/ plano and plano/concave substrate codes begin with HR. Plano/convex sustrate 

codes begin with HX. Radius code is omitted for plano/plano substrates. 

Example 1 : Si; plano/plano; 25.4㎜ diameter; 10.6μm; 45。; unpolarized : HR 2612 S LR A06 4 U 

Example 2 : CaF₂; plano/convex; 12.7㎜ diameter; 5m radius; 2.94 μm; 0。: HX 1312 C 05 LR 294 0 

Other substrate materials, specifications, wavelengths, radII and angles of incidence can be provided 

upon request. Please contact our sales department for assistance.
