BK7-LNPBSP-12.7-1064 12.7 mm Dia. N-BK7 50:50 (R:T) Laser Line Non-Polarizing Plate Beamsplitter; t=3mm 1064nm

This is a BK7-LNPBSP-12.7-1064 12.7 mm Dia. N-BK7 50:50 (R:T) Laser Line Non-Polarizing Plate Beamsplitter, available from Simtrum. The beamsplitter has a diameter of 12.7 mm and a thickness of 3 mm, designed with a circular base shape. It is made of n-bk7 schott material, a type of borosilicate glass known for its excellent optical properties, including high transparency and low auto-fluorescence.

The beamsplitter is designed to operate at a wavelength of 1064 nm, making it suitable for use in various applications, such as laser systems and interferometry. The coating on the front surface is sim npbs 50 1064 45, a non-polarizing beamsplitter coating that provides a 50:50 (R:T) split ratio for the incident light at the specified wavelength. This means that the beamsplitter reflects 50% of the incident light and transmits the remaining 50%.

The beamsplitter's shape is thin lens, which suggests that it may have some focusing or diverging properties. However, the item data does not provide specific information about these properties. Therefore, users should consult the vendor for more detailed information.
