LAYER DESIGN

SPECTRAL REFLECTANCE

Single-layer Caoting
E 525- AR

Application:
For mineral glasses with refractive indices
n_d = 1,45 up to 1,9.

The reflectance ρ depends on the refractive index of the substrate, e.g. :
BK7 n_d = 1,52 ρ = 1,3%
SF6 n_d = 1,80 ρ = 0,08%
for the central wavelength
λ_s = 525 nm.

V-Coating V 525- AR-C

Application:
For substrates with low refractive indices.

Residual reflection ρ ≤ 0,2%
for central wavelength
λ_s = 525 nm.

Multi Coating
M 400/680-MC

Application:
For mineral glasses with refractive indices
n_d = 1,45 up to 1,9.

Reflection characteristics:

λ [nm]	ρ _max[%]	ρ _Ø [%]
400	1,0	-
420	0,5	0,3
640	0,5	0,3
680	1,0	-

Broadband Reflection
M 400/1000-MC

Application:
For mineral glasses with refractive indices
n_d = 1,45 up to 1,9.

Reflection characteristics:

λ [nm]	ρ _max[%]	ρ _Ø[%]
400	4,5	-
425	2,0	1,0
1000	1,5	1,0
1100	4,5	-

Hydrophobic Multilayer
M 400/680-MRC

Application:
For mineral glasses with refractive indices
n_d = 1,45 up to 1,9
and heat-sensitive optical components, e.g.
plastics, cemented parts,
CR39, Polycarbonate,
LEXAN, ...

Characteristic:
Hydrophobic surface attributes.

V-Coating V 525-AR-O

Application:
For substrates with low refractive indices.

Residual reflection ρ ≤ 0,2%
for central wavelength
λ_s = 525 nm.

Characteristic:
