Semrock Launches Optical Bandpass Filter for Laser Applications

Semrock announced that it has rolled out a new widely tunable optical filter that enables imaging in the near-IR region. The TBP01-800/12 thin-film optical filter is the latest addition to the VersaChrome tunable filters and has a wavelength tuning range of more than 100 nm.

The VersaChrome filters provide wavelength tenability in a diverse wavelength range by altering the incidence angle and without changing the spectral performance. The filters integrate diffraction grating’s center wavelength tuning versatility with the benefits of thin-film optical filters. The advantages of thin-film optical filters include steep edges and high average transmission.

The optical bandpass filters cover a diverse wavelength ranging from 390 nm to 800 nm. The filters are suitable for high-throughput spectroscopy, hyperspectral imaging, and fluorescence microscopy applications. The filters have enhanced optical quality and improved polarization insensitivity, making them ideal for various laser applications. They are also useful for all kinds of optical systems that are likely to gain from the two-dimensional imaging performance of the thin-film filters.
