The Thorlabs BP108 Pellicle Beamsplitter is a versatile and high-quality optical component, specifically designed for use in the ultraviolet (UV) region of the spectrum, with a central wavelength of 92 nm. This uncoated pellicle beamsplitter is manufactured with a thickness of 400-2400 microns, providing a wide range of applicability based on the specific requirements of your UV experiment or application.
The BP108 Pellicle Beamsplitter is constructed from a high-purity, UV-transparent material, ensuring minimal absorption and scattering of the incident light. Its pellicle structure allows for efficient operation with low-intensity UV sources, as well as making it an excellent choice for applications that require high beam stability and minimal thermal effects.
This beamsplitter features a 50:50 transmission/reflection ratio, meaning that it evenly divides the incident light beam into two equal parts, one transmitted and the other reflected. This 50:50 ratio can be beneficial for applications such as UV interferometry, where the equal division of the beam is essential for obtaining accurate results.
The uncoated design of the BP108 Pellicle Beamsplitter eliminates the need for additional antireflection coatings, making it a cost-effective solution for UV applications. However, it is important to note that the lack of coatings may result in higher reflectivity compared to coated beamsplitters.
In conclusion, the Thorlabs BP108 Pellicle Beamsplitter is a reliable and versatile UV optical component well-suited for various applications, such as UV interferometry, UV spectroscopy, and UV lithography. Its wide thickness range, high transparency, and 50:50 transmission/reflection ratio make it a valuable tool in the field of UV optics.
