Cube Beamsplitter
A beamsplitter is a core element of an optical system used to split incident light into two beams (reflection and transmission) in a specific ratio. Depending on the principle of beamsplitting, materials, and coatings, they can be divided into various types. Difference between Beamsplitter, Polarizing Beamsplitter and Non-Polarizing Beamsplitter Beamsplitter: sensitive to incident polarization, the angle of linear polarization affects the spectral ratio. If the incident light is natural light or circularly polarized light, the light will be split according to 50:50. Split beam when only share the energy, the ideal device under the two-way light polarization state or the original appearance of the incident light, the actual process defects will cause a little bit of de-polarization. Almost no absorption of light intensity. Polarizing Beamsplitter: sensitive to incident polarization, the angle of linear polarization affects the spectral ratio. If the incident light is natural light or circularly polarized light, the light will be split according to 50:50. When splitting the beam, in addition to distributing energy, the two outgoing beams must be linearly polarized, and one beam is parallel linearly polarized and the other is perpendicularly linearly polarized, with the two linearly polarized directions differing by 90°. Non-Polarizing Beamsplitter: insensitive to polarization, regardless of what the incident light polarization state will not affect the incident light splitting ratio, splitting ratio in any case is 50:50. Beam splitting time only split the energy, the ideal device out of the two light polarization state or the original, the actual process defects will cause a little bit back polarization. There is a certain absorption of light intensity.

Harmonic Beamsplitter OMB05-R355-T532&1064 Beam Splitters Jcoptix
Optical element material: UV Fused Silica Clear Aperture Dimension: > 80% of Diameter Angle of Incidence: 45°
Harmonic beamsplitters, sometimes called harmonic separators or dichroic filters, are designed to separate Nd:YAG laser harmonics at 45° incidence. They provide high reflection (99.5%) and transmission (95%) at specified wavelengths. The front surface has a beamsplitting coating designed for the reflected beam, while the rear surface has a V-type antireflection coating for the corresponding transmitted wavelength, reducing interference between front- and rear-surface reflections and minimizing reflection losses. JCOPTIX currently offers three wavelength configurations for different applications: 1064 nm reflection and 532 nm transmission; 532 nm reflection and 1064 nm transmission; 355 nm reflection and 532 and 1064 nm transmission. Contact technical support for other wavelength configurations.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
