Beam splitter (BMS-007)
BMS-007 is a beam splitter. Consider it when you need to split light between a main optical path and a monitoring detector or second device. The reference spectrum describes the transmitted path; choose the required reflection ratio and angle of incidence with KUPO.
Optical performance
- Measured wavelength range: 300-1100 nm. Performance outside this measured interval is not established by this curve.
- 400-500 nm: Approximately 43.2-53.1% transmission in the measured curve.
- 500-600 nm: Approximately 50.1-53.7% transmission in the measured curve.
- 600-700 nm: Approximately 50.2-53.9% transmission in the measured curve.
- Reflection and working angle: Specify the required reflected path, polarization and angle; transmission alone does not establish those properties.
- Average measured transmission, 530-1070 nm: 50.739%. Calculated from the factory sample data.
- Factory working-angle designation: The matching factory worksheet is designated for 45 degrees angle of incidence. Confirm polarization and final acceptance conditions for the supplied configuration.
- Customization: We can customize stock and sample-book designs. Tell us the wavelength response, size and operating conditions you need.
These values come from the measured samples and help you choose a starting design. We will agree the final specification for your order. Custom versions have their own specifications and measured curves.
Applications to consider
- Illumination monitoring: Consider it for sending part of a beam to a monitoring detector. Specify the required throughput in both paths at the working angle.
- Dual-path imaging: Consider it for sharing light between a camera and another imaging or viewing device. Account for polarization, wavefront requirements and wavelength-dependent balance.
- Instrument integration: Compare the transmission profile with the required spectral band, then confirm reflection and geometry before finalizing the optical layout.
Choosing this filter
- Confirm transmitted and reflected specifications separately, including polarization and angle of incidence. The supplied transmission curve is not a measurement of the reflected path.
Custom options
Start with this stock or sample-book design, then tell us what you need to change. We can discuss the wavelength bands, transmission, blocking, angle, glass material, size and operating conditions with you, and agree a specification for your custom filter.

Questions about BMS-007
What does the BMS-007 curve tell me about the two output paths?
It gives the transmitted-light response, including 50.739% average transmission over 530-1070 nm. It does not independently measure the reflected path. Specify the response you need in each path rather than assuming they are equal.
Can I choose BMS-007 before fixing the beam geometry?
The matching factory worksheet is designated for 45-degree incidence. For BMS-007, include the wavelength range and polarization of each path. A transmission curve alone is not enough to establish the split for a different geometry.
