Product Case Studies

A cubic beam splitter is formed by coating a film on the inclined surface of a right angled prism and then bonding the same right angled prism together. It can avoid the astigmatism of the flat beam splitter, and the coating is not directly exposed, making it less prone to damage and corrosion. Compared with a flat beam splitter, the reflection and transmission optical paths of a beam splitter are equal. When transmitting light, the beam splitter prism does not have the impact of light deviation, so there is no problem of beam translation, ghosting, or interference. Used for spectroscopy and imaging. No need for long-term calibration when incident at a 45 ° angle.

Maipu Optoelectronics offers a variety of plate type beam splitters: UV fused silica (250-1700 nm), IR fused silica (900-2600 nm), calcium fluoride (1-8 m), zinc selenide (1-14 m), covering the UV mir wavelength range.

UV fused silica beam splitter compensation plate can also be used.

We also provide beam splitters for Nd: YAG wavelengths (1064 nm and 532 nm)

The working principle of a cube polarized beam splitter is based on the polarization characteristics of light. When unpolarized or mixed polarized light is incident on the surface of a beam splitter, s-polarized light (electric field vibration direction perpendicular to the incident surface) and p-polarized light (electric field vibration direction parallel to the incident surface) will be processed by polarizing films in different ways. Usually, one polarization state of light (such as s-polarized light) is directly transmitted through a polarizing film, while the other polarization state of light (such as p-polarized light) is reflected. In this way, the originally mixed beam is split into two beams of light with different polarization states.

characteristic

• High polarization purity：The cube polarized beam splitter can provide highly pure polarized light, suitable for systems that require high polarization purity.
• high damage threshold：Due to the fact that the beam does not need to pass through a thin film, this type of beam splitter is suitable for high-power applications and has a high laser damage threshold.
• Compact design：The cubic shape makes the integration of this spectroscope in optical systems more compact.
• Wide band applicability：By selecting the appropriate polarizing film, the cubic polarizing beam splitter can be adapted to different wavelength ranges.
