Cube Beam Splitter




Broadband Polarizing Cube Beam Splitter


Broadband Polarizing Cube Beam Splitter

A cube polarizer consists of a pair of cemented precision right-angle prisms to form a cube with low output beam distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for a specified wavelength range. The four outer faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses. An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 500:1 and is used as a broadband polarizer in a standard cube configuration.

Coating Specs:
Substrate Material : BK7,SF2,SF15 etc.
Coating technology : Electric beam deposition
Coating type : Multi layer dielectric
Wavelength range :500-600 nm, 600-800nm also as per custom requirement
Coating performance :Tp/Ts>=500:1, Tp >95% and Rs> 99.8%
Angle of incidence :45 degree
Antireflection coating : Broadband (R<1%)
Clear aperture : > 85 % of the specified aperture
Adhesion and durability : As per MIL-C-675

 

Applications: Projection Systems and signal processing Color separation and recombinatio

Note: Other custom made coatings can be done.

Laser Line Non-Polarizing Beam Splitter

Laser line non-polarizing cube beamsplitters are insensitive to the polarization of an incoming beam. The hypotenuse of one of the prisms is coated with a multilayer all-dielectric non-polarizing beamsplitter coating optimized for specific laser lines. They provide true 50/50 beamsplitting without altering the beam polarization. Incommg beams are both transmitted and reflected 50%, with the s and p-polarized components matched to within 3%. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses at the laser lines.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 








Non-Polarizing & Polka Dot

Dichroic coatings will transmit some part of the spectrum while reflecting the other part. In a cube beamsplitter it is hard to achieve the non-polarization condition especially when the angle of incidence is steeper. This beamsplitter coating will transmit the visible spectrum except the specified color (Red or Blue or green). All the other four sides of the cube beamsplitter are coated with broadband antireflection coating.

Applications:

Color separationand combination,projection systems and aiming sights

Note: Other custom made coatings can be done.

 

Polka Dot Beam Splitters

Polka dot beamsplitter is vacuum deposited aluminium coating with protective dielectric layer on ultraviolet grade fused silica substrate. Coating is deposited in the circular/ square type patterns of preferred dimension and spacing depending on the input beam size. When this beamsplitter is placed in the input beam path, it divides the beam energy into equal halves in transmission and reflection. This coating bears the advantage of being insensitive to the angle of incidence and color neutral.

Coating Specs:
Substrate Material : UVFS
Coating technology : Electric beam deposition
Coating type : Metallic aluminium + protective overcoat
Wavelength range : 190-1100 nm
Coating performance : Transmission: 50 ±5% Reflection: 50 ±5%
Angle of incidence : 0-45 degree
Clear aperture :> 85 % of the specified aperture
Adhesion and durability : As per MIL-C-675C
Required dimensions

 

Applications:

As equal energy dividers in spectrophotometers to sample and reference beam

Note:

A, b, d and D (in mm) should be specified. Square type dot patterns also can be done.
