IdealPhotonics' bandpass filter kit is a combination of optical elements designed with multi-layer dielectric films to allow only specific narrow bands of light (such as within the center wavelength ± half-width range) to transmit efficiently, while blocking other wavelengths.Features include multi-band precise gating (narrowband/broadband), high transmittance and deep cutoff, durable hard coating, and suitability for fluorescence analysis, spectral detection, and laser systems.
