MDFM-T Microscope Filter Module Turret MTCP2

External dimensions: 68 mm × 68 mm × 35 mm Internal dimensions: 64 mm × 64 mm × 31 mm Color: Transparent

The gel storage box for lenses, prisms and filters belongs to the self-adhesive box series. A gel layer secures precision devices for storage, handling and transport. Refer to this page's parameters and actual confirmation for dimensions, materials, compatibility and operating conditions. It is used for packaging, storage, handling or display. See the parameters for dimensions, materials and structure; contact Kangpaike to confirm samples, specifications, materials or customization.

Attenuation Wavelength: 200nm-1550nm Absorptance: OD=0。 5、OD=1、OD=2、OD=3、OD=5、OD=10、OD=20、OD=30 Ultraviolet Wavelength: 250nm to 380nm; transmission after absorption 20%, 50%

The neutral-density (ND) filter, also called a neutral-gray-density filter, attenuates light nonselectively and uniformly across wavelengths. It reduces intensity without changing the object's original colors, faithfully reproducing scene contrast.

Diameter: 2 mm to 200 mm Diameter Tolerance [Or Customer-Specified Dimensions]: +0.00/-0.1 Or Customer-Specified Dimensions Material: N-BK7, H-K9L, sapphire, fused silica (JGS1), Caf2, ZnSe, Si and Ge.

Shortpass filters transmit shorter wavelengths and block longer wavelengths. They are mainly used in beauty instruments, police multiband inspection instruments, high-intensity flashlights, stage-light covers, four-wheeled vehicles, iris recognition, facial-recognition attendance systems and optical instruments.

Narrow bandpass filters transmit a small band of light; a narrower band gives purer light. Sandi Optoelectronics produces standard narrow bandpass filters at 270nm, 311, 360, 380, 473, 532, 650, 780, 808, 850, 904, 940, 1064 and 1900nm. Applications include biometrics, touchscreens, vehicle wheel alignment, medical equipment, barcode scanning, infrared cameras, night vision, laser ranging, fingerprint recognition and laser systems.

Temperature: >90% Closed [200-1200nm]: OD6 200-1200nm Flatness [@633nm]: 1/4 lambda@633nm

Fluorescence filters extract fluorescence energy or images in fluorescence systems. Strong stray-light isolation and low autofluorescence suit PCR, fluorescence immunoassay and microscopy. Blocking typically exceeds OD5, optical density OD=-lgT. As key biomedical/life-science components, they offer deep blocking, low autofluorescence, good transmission and surface form. High-quality versions use one colorless transparent glass substrate coated on both sides, improving imaging over bonded multilayers or colored-glass-assisted blocking, though harder manufacture raises cost. A typical set comprises excitation filter, emission filter and dichroic mirror; some systems omit the dichroic, and laser excitation may eliminate the excitation filter. Excitation filter: Passes only excitation wavelengths; bandpass has largely replaced shortpass. An engraved arrow indicates recommended light direction. Emission filter: Passes sample fluorescence and blocks other wavelengths. Emission is longer/redder than excitation; bandpass or longpass types are used, with direction arrows. Dichroic mirror/beamsplitter, also called a color separator, is mounted45° to the microscope path. It reflects excitation and transmits emission, with reflectance>90% and transmission>90%. Rejected bands reflect rather than absorb; transmitted/reflected colors are complementary.
