Plano Optics

The LINOS Plano Optics 

LINOS is known for high-quality plane plates 

from optical glass, fused silica and sapphire, 

as well as a variety of prisms, filters, beam 

splitters, reticles and dispersion plates. We 

can offer support for all your applications 

that require precise planarity and flawless 

surfaces. High-quality materials ensure the 

best possible transmission and consistent, reliable 

quality standards in all LINOS products. 

In production, we place a high value on the 

narrowest possible angular tolerances and 

the best parallelism, integrity and fit. LINOS 

plano optics and their coatings are manufactured 

using the latest machines and are subject 

to constant, meticulous quality control. 

LINOS stands for lasting precision! 

Our quality criteria: 

• High-quality glass materials from 

established manufacturers 

• Many years of experience in precision 

optics production 

• The narrowest possible production 

tolerances 

! 

Special features: 

Many components are available in 

mounts compatible with LINOS 

bench systems. Prisms can also be 

found in the Prism Wizard of the 

WinLens 3D program. 

Ideal areas of application: 

Beam deflection, beam splitting, 

measurement tasks, view panels, 

and more.

Variable Beamsplitter Plates 

Variable Beamsplitter Plates 

Variable-beamsplitting-ratio dielectric 

coatings 

for varying reflectance / transmittance 

ratios over the spectral ranges 

λ = 400 to 800 nm. 

Reflectance/transmittance vary with 

distance (length of travel) along 

beams plitter plates. 

• Ideally suited as variable-transmittance 

output couplers for dye lasers 

• Ideally suited for equalizing intensities 

of object and reference beams in 

holography and interferometry 

• Act as variable wavelength selectors 

when illuminated by polychromatic 

light 

• Second surfaces broadband AR-coated
