BK7-NPBSP-25.4-900-1200-30:70 25.4 mm Dia. N-BK7 70:30 (R:T) Broadband Non-Polarizing Plate Beamsplitter; t=3mm 900-1200nm

This product is a broadband non-polarizing plate beamsplitter, designed and manufactured by Simtrum. It is specifically engineered for use within the wavelength range of 900-1200nm, making it suitable for a variety of applications in the near-infrared spectrum.

The beamsplitter features a circular geometry with a diameter of 25.4mm, providing a versatile size that can be incorporated into many optical systems. The thickness of the beamsplitter is 3mm, adding to its robustness and durability.

The material of the beamsplitter is N-BK7, a type of borosilicate glass that is known for its excellent optical properties. This material is sourced from Schott, a leading manufacturer in the field of optical glass.

The beamsplitter's coating is a sim npbs 900-1200 45, which is applied to the front surface. This coating enhances the beamsplitter's performance within the specified wavelength range.

The beamsplitter is designed in the shape of a thin lens, which helps to minimize optical aberrations and distortions. This is particularly beneficial in applications that require high precision and accuracy.

The physical data of the beamsplitter indicates that it has a reflection of 0.7 and a transmission of 0.3 at the base wavelength of 1064nm. This ratio can be useful in determining the optimal positioning and alignment of the beamsplitter within an optical system.
