Mok Optics takes you to understand beamsplitters

Definition of Beamsplitter

Beamsplitters are important optical devices that split or combine light beams, but due to their low absorption, this product is more suitable for laser applications. The cube is designed for low-power applications and provides a convenient and protected design. The efficiency of beamsplitters is similar to that of other optical lenses, and is also affected by their coating specifications.

Beamsplitter Overview

Beamsplitter Plates

Spectrum: Broadband Wavelength
Properties: Suitable for high-power lasers. It is important to consider that the two beams generated propagate along different optical paths, which is determined by the angle of incidence and the thickness of the beamsplitter plate.
Single Wavelength Performance: Yes

Beamsplitter Cubes

Spectrum: Broadband Wavelength
Advantages compared to beamsplitter plates: Both reflected and transmitted beams propagate along the same optical path.
The transmitted beam remains undistorted and unshifted. Provides stability and compact design. Simplifies operation and alignment.
Single wavelength performance: Yes

Pentaprism beamsplitter cube

Spectrum: Broadband wavelength (630-680 nm)

T/R ratio: 20%/80% ±5%

Features: Consists of a pentaprism and a wedge.

Similar to the beam splitter cube, it has the following features: Transmitted beam is not distorted or offset.

Stable and compact design. Easy to operate.

Polarizing beamsplitter cube

Spectrum: Broadband wavelength

Features: Used as a polarizer, beam splitter or beam combiner.

Produces two output beams: p-polarized beam (parallel to the input) and s-polarized beam (orthogonal to the input).
