Are there any beam splitters with no attenuation

How to Select a Beamsplitter

These beamsplitters can separate components of a laser beam based on wavelength, or to truly combine different wavelengths (or bands) with minimal loss, and are thus suitable for high power

Beam Splitter Selection Guide

Our beam splitters are made from high grade glass material with laser grade surface flatness & surface quality for tighter tolerance on the splitting ratio.

Beam Splitter Input-Output Relations

The elements of the beam splitter transformation matrix B are determined using the assumption that the beamsplitter is lossless. While a beamsplitter is never lossless, it is a good approximation for most

What are Beamsplitters?

Options range from laser beam combiners designed for specific laser wavelengths to broadband hot and cold mirrors for splitting visible and infrared light. This type of beamsplitter is commonly used in

Beam Splitter Cubes

Non-polarizing beam splitters split the incident light with an R/T ratio of 50%. They are designed for exactly one wavelength and do not have any influence on the polarization of the beam to be split.

In its most common form, a cube, a beam splitter is made from two triangular glass prisms which are glued together at their base using polyester, epoxy, or urethane-based adhesives. (Before these synthetic resins, natural ones were used, e.g. Canada balsam.) The thickness of the resin layer is adjusted such that (for a certain wavelength) half of the light incident through one "port" (i.e., face of the cube) is reflected and th

Beamsplitters for Every Application

Our non-polarizing beam splitters are used in laser beam manipulation and interferometry, and we offer both plate and cubic options. These dichroic mirrors can be customized with a metallic coating for

Thorlabs · Beamsplitter Cubes

Our beamsplitter cubes can be purchased premounted in cubes that are compatible with our lens tube and cage systems.

Large beam size, multi mirror optical set up with small power light source and supports high power laser light splitting. Polarization at 45 degree (AOI) or circle polarization light with no power loss detected.

Beam Splitters – optical power splitter, beamsplitter, thin-film

Beam splitters are devices for splitting a laser beam into two or more beams. There are different types, including polarizing and non-polarizing versions.

Beam splitter

To reduce loss of light due to absorption by the reflective coating, so-called "Swiss-cheese" beam-splitter mirrors have been used. Originally, these were sheets of highly polished metal perforated with
