These beamsplitters are coated with aluminum and SiO protective overcoat in a "polka dot" pattern. The pattern is a series of aluminum dots, 2.5 mm in diameter, separated by a 3.2 mm center-to-center distance. Light is reflected by the metal-coated areas of the beamsplitter and transmitted through the uncoated areas of the beamsplitter.
Nov 30, 2021 These Polka Dot Beamsplitters are made from B270 glass and provide high transmission over the 350 nm - 2.0 µm spectral range. They can be used from 0 to 45° AOI with only negligible changes to the reflected and transmitted intensity. Light should be incident on the aluminum-coated side to maximize the reflected intensity.

Variable beamsplitters are sensitive to changes in the angle of incidence (AOI) with reflection:transmission ratio change based on AOI. When used with a laser, tilting a variable beamsplitter will change the transmitted energy so you can tune the laser power for your application. This allows power adjustments without adjusting the laser itself.

What is a plate or "mirror-type" beamsplitter? A beamsplitter is an optical component that divides light (i.e., a beam) into two separate portions (beams). When the component is inserted into an optical path at a specific angle (typically 45°), a portion of the beam will be diverted (reflected) in a different direction (typically 90° from the ...
The way to use them depends on the optic, but always wipe slowly and clean the edges first. Glass-cleaning solvents will streak, and tissue paper or a t-shirt will scratch, so always clean optics with reagent- or spectrophotometric-grade solvent and a low-lint tissue manufactured for cleaning optics. Always use lens tissue with a solvent, because dry lens tissue can scratch
The front surface is coated with a multilayer all dielectric non-polarizing beamsplitter coating optimized for a specific laser line. The back surface is coated with a multilayer dielectric antireflection coating to minimize surface reflection losses and eliminate ghost images.

Overview. Our Calcium Flouride beam splitting plates are designed for use in the 2-8 µm wavelength range. Coated with a multi-layer dielectric beamsplitter coating, the optics are optimized for IR use with a 50% +/- 10% splitting ratio. 50/50 beamsplitting for 2 to 8 micron wavelengths. Thermal shock resistance and low absorption.
The coating on a teleprompter (beamsplitter) mirror is thinner, allowing more light to pass through. It's more transparent and less opaque than a standard two way mirror, which is intended for security, not viewability. The coating of a teleprompter mirror is dielectric instead of metallic, which allows it to be color neutral (untinted).
The simplest configuration for a beamsplitter is an uncoated flat glass plate (such as a microscope slide), which has an average surface reflectance of about 4 percent. When placed at a 45-degree angle, the plate will transmit most of the light, but reflect a small amount at a 90-degree angle to the incident beam.

In the near-IR region a beam-splitting film should be very thin. In this case it is necessary to use a low-absorption dielectric coating, which is deposited on a suitable substrate plate. A thin Ge layer deposited on a KBr substrate, with a KBr compensating plate, is a good beamsplitter in the wavenumber region 1000–4000 cm −1.
