Pericle Beam Splitter
Beam splitter without ghosting 【Features】 ○ Since it is a beam splitter with a thin film of 5μm or 2μm, reflections from the back surface do not create ghosts. ○ In addition to standard round and rectangular frames, custom frames can also be made. ● For more details, please contact us or download the catalog.
Less ghosting than a plate beam splitter.
Produced by Spectral Optics, the cube-shaped beam splitter is used because it has no angular displacement and fewer ghosts than plate beam splitters. It has a dielectric partial reflection coating on the inside. All four sides are coated with anti-reflective (AR) coating for specific wavelengths. Please input collimated, parallel light. The bonded cube beam splitter can be used up to 1064nm at 1J/cm². The new molecular fusion bonding technology from Spectral Optics allows for permanent bonding, creating an optically connected unit. This enables their use in very high energy/high power laser applications. No optical cement or other materials that degrade coating performance are used.
The laser beam is split into two orthogonal polarization components.
The cube beam splitter consists of two right-angle prisms coated with a special dielectric coating. The polarizing cube beam splitter divides a laser beam into two orthogonal polarization components or is used to combine them into one beam. It transmits P-polarization and reflects S-polarization at 90°. In low-power applications, the cube is assembled using a transparent refractive index matching adhesive at the junction with two 90° right-angle prisms. It can be used up to 1064nm at 1 J/cm². Please enter from the marked surface. Optical contact cubes offer good beam quality, high damage thresholds, a wide wavelength range, and wavefront accuracy, but they are not mechanically stable due to the fragile nature of the optically contacted interface. The new molecular fusion bonding technology from Spectral Optics permanently bonds without using cement or other materials that degrade coating performance.
Broadband polarizing beam splitter cube made from SF2 glass.
Spectras Optics supplies broadband polarizing beam splitter cubes made from SF2 glass. Since SF2 glass has a high refractive index, the broadband polarizing cube beam splitter can be used for high-performance wideband applications. For low and medium power lasers, up to 1 J/cm².
A revolutionary polarization-independent beam splitter that can be used with high-power lasers.
Spectral Optics' TrueSplit is a groundbreaking product in beam splitter technology. Most unpolarized beam splitters use hybrid metal coatings or optical cement that absorbs energy. TrueSplit does not use adhesives with hard dielectric coatings. As a result, it achieves absorption below 3%, P-S polarization performance, and a damage threshold of over 20 J/cm². Furthermore, it can achieve almost any R/T ratio (not just 50/50) and nearly any wavelength. The standard unit has a size of 2 ½ inches x 2 ½ inches with an effective diameter of 5/8 inches, and other sizes can be manufactured.
Plate-type beam splitter for high-power lasers.
Depending on the application, cube beam splitters may not be suitable, and instead, plate beam splitters are used. For the highest levels of wavefront and power handling, conventional coated plate types such as BK7 or fused silica are excellent choices. Spectral Optics offers various R/T ratios of standard plate beam splitters, all coated with dielectric coatings. These are designed for specific wavelengths and polarizations (S-polarized, P-polarized, or unpolarized), at 45° (or other incident angles). The backside is treated with anti-reflective (AR) coating.
Beam splitter for separating the fundamental wave and harmonics of a laser.
Regular plate harmonic beam splitter and ultra-thin harmonic beam splitter are two types. High-energy harmonic beam splitters are similar to dichroic beam splitters. They are designed to separate the fundamental wave and harmonics of a laser. Spectral Optics supplies harmonic beam splitters for Nd:YAG lasers and Ti:sapphire lasers. A single-sided high-energy dichroic coating reflects over 99.5% of the target wavelength while transmitting other wavelengths. For wavelengths longer than the target wavelength, it transmits over 90%, and for wavelengths shorter than the target wavelength, it transmits over 85%. The backside is coated with high-energy AR coating for the transmitted wavelengths. If the beam size is small, less than 3mm, a minimum deviation angle is required, and an ultra-thin beam splitter is necessary.
