Biochemical analysis is one of the detection methods often used in clinic. It determines various biochemical indexes through the analysis of blood or other body

Fluorescent filters generally include three combinations, namely excitation filter, emission filter and dichroic mirror. Excitation filter (excitation filter, exciter filter, excitation filter): in fluorescence microscope,

The red light filter can only be made of plastic or special dye, and so on. The refractive index of the glass sheet is similar

Central wavelength (CWL): the wavelength used by the filter in practical application. If the main peak value of the light source is 850nm LED lamp,

Soft coating Soft coating is a multilayer film composed of zinc sulfide, refrigerant and sometimes even silver. For conventional interference filters, the coated components are

Some people may think that in the modern era of digital photography, neutral density and polarization filters are not needed. Okay, No. Although many filters

Neutral density (nd) filter: it can attenuate the light intensity. After passing through the neutral density filter, the light from the visible light region to

Dichroic filter is a very accurate color filter, which is used to selectively pass through light and reflect other colors from a small range of

Long wave pass filters are inseparable from our lives. Today, let’s take a look at the filters in our lives and where they are? For

1. Distinguish filters by spectral band: The filter is divided into ultraviolet filter, visible filter, near-infrared filter, infrared filter and far-infrared filter according to the
