Solution The pulmonary function tester consists of a host, a flow sensor, and a nose clip. It is suitable for respiratory medicine, chest medicine, occupational disease prevention and control institutions, hospital physical examinations, outpatient clinics, homes and other environments. It is used for pulmonary function…
Key Types of Flow Cytometry Optical Filters Bandpass Filters:Allow only a specific wavelength range (or band) to pass through, blocking wavelengths outside of this range.Typically described by a center wavelength (CWL) and a bandwidth (full width at half maximum, FWHM), such as a 530/30 filter,…
Main features High reflectivity: It has extremely high reflectivity at 650nm wavelength to ensure that light of a specific wavelength does not leak.Broadband transmission: It allows light of other non-target bands to pass through, which is suitable for applications that separate specific wavelengths.Durability: High-quality coating…
Spectral Range Reflection Range: 355-415 nm mirrors generally have a reflectivity between 99% and 99.9%, with excellent reflection in the 355 to 415 nm range, while other wavelengths may have lower reflectivity to avoid unnecessary interference.Spectral Control: This mirror is designed for UV to near-visible…
Key Features Customized Geometries: These mirrors may have unique shapes, including freeform surfaces, asymmetric curves, or non-standard polygons. This flexibility allows them to direct or focus light according to precise application requirements, supporting functions like beam shaping, wide-angle reflection, and field-of-view expansion. Tailored Reflective Coatings:…

Laser systems: Provide a protective barrier for sensitive laser optics,…
Product Features Selective transmission and reflection: The dichroic mirror can precisely control the wavelength. Through the film design, it can achieve high transmittance for light of specific wavelengths (red light, blue light), effectively reflect the green light band, and ensure the accuracy and stability of…

How an Infrared Variable Neutral Density Filter Works The IR VND filter typically consists of two polarizing films or elements with adjustable relative rotation. The filter’s density—and thus the level of light attenuation—can be varied by rotating these polarizing elements relative to each other. In…
A polarizing film is an optical filter that selectively transmits light with a specific polarization while blocking other orientations. This film is designed to either absorb or reflect light waves with certain orientations, thereby creating a polarized output. Polarizing films are widely used in applications…
