HO-MPCBS-25C 25 mm Dia. 70:30 (R:T) N-BK7 Plate Beamsplitter; t=6mm 400-700nm

This is a 25 mm diameter beamsplitter, specifically the HO-MPCBS-25C model from Holmarc Opto-Mechatronics. It is designed to split incoming light beams at a 70:30 ratio, with 70% of the light being reflected and 30% transmitted. The beamsplitter is made from N-BK7 Schott glass, a popular material known for its excellent optical properties and wide transmission range.

The beamsplitter has a thickness of 6mm, which is relatively thin, making it suitable for applications where space is a constraint. It is coated on both sides with specific coatings for enhanced performance. The front side is coated with 'hol mpbs703040070045', while the back side is coated with 'hol mgf2 45 aoi'. These coatings are designed to optimize the beamsplitter's performance within the 400-700nm wavelength range.

The beamsplitter is in the shape of a thin lens, which can be beneficial in certain applications due to its focusing capabilities. The physical data of the beamsplitter indicates that the reflection coefficient is 0.7, and the transmission coefficient is 0.3, aligning with the intended 70:30 split ratio.
