Bandpass filter

Designing and manufacturing bandpass filters for various applications.  

Fluorescence Microscopy

In fluorescence microscopy used for labeling cells and biological tissues, filters are essential for observing specific fluorescence.

Multispectral Imaging

Optical filters are utilized in sensors to detect light at specific wavelengths for monitoring atmospheric pollutants and particles.

Optical Coherence Tomography (OCT)

In optical sensors used for measurements and examinations within medical devices, filters are necessary to utilize light at specific wavelengths.

Raman Spectroscopy

In Raman spectroscopy, used to investigate the composition and structure of chemicals, analysis is conducted using light at specific wavelengths.

Flow Cytometry

Devices for testing blood coagulation employ optical filters to use light of specific wavelengths for examination.

In all these applications, the choice of bandpass filter parameters, such as central wavelength and bandwidth, is critical to isolating the desired spectral information.
Properly selected and calibrated bandpass filters help improve image quality, enhance contrast, and provide valuable insights into biological samples, making them essential components of many biomedical imaging systems.
Thanks to our innovative coating technology, steep and inclined transmittance can be achieved with high OD values.
