Product Description Product Description As a core optical component for regulating light intensityCharacteristicsPrecise Light Control, Quantifiable Attenuation:The degree of attenuation is precisely marked in "dB" units (e.g., 3dB halves the light intensity, 10dB reduces it to 1/10). Different types can meet fixed or dynamic adjustment needs, avoiding errors caused by overly strong or weak light intensities.Flexible Wavelength Adaptability:Covers specific wavelengths (such as 1310nm and 1550nm for fiber-optic communications) and a wide wavelength range (e.g., 400-1600nm). Some models can selectively attenuate specific wavelengths, adapting to various optical signal regulation scenarios.Strong Safety and Stability:High damage threshold models can withstand high-power lasers (e.g., made of metal films or heat-resistant glass materials). Absorptive attenuators reduce light reflection interference by converting light energy into heat, while reflective attenuators offer high precision but require attention to angular effects.Convenient Operation, Wide Scene Adaptability:Fixed attenuators are ready to use without adjustment; variable attenuators can be manually or automatically adjusted (e.g., via knobs or electric control), meeting dynamic light intensity needs in laboratories and industrial testing.Main FunctionsLight Intensity Regulation, Device Protection:The core function is to reduce incident light intensity, preventing damage to photodetectors, receivers, or sensors caused by overly strong light signals (e.g., avoiding receiver overload in fiber-optic communications and protecting photometric instruments in laboratories).Signal Balancing and Optimization:In multi-wavelength systems (such as fiber-optic networks and projection displays), wavelength-selective attenuators balance the intensity of different wavelength light signals, ensuring uniform and stable signals; adjusting light intensity during projection or imaging to avoid glare or blurriness.Precise Control in Experiments and Testing:In laser experiments and optical testing, variable attenuators finely adjust light intensity to simulate different lighting conditions and obtain accurate experimental data (e.g., material light response testing, detector sensitivity calibration).Safety Protection and Adaptive Applications:In high-power scenarios (such as laser surgery and industrial laser processing), absorptive attenuators reduce laser power to a safe range, ensuring equipment and personnel safety; wide-wavelength models adapt to multi-spectral light source regulation, offering strong versatility.Application RangesFiber-Optic Communications and Optical Networks:Used in fiber-optic transmission systems to regulate optical signal intensity, preventing receiver overload and damage due to overly strong signals, ensuring communication stability.Scient ific Research and Laboratory Testing:In laser experiments, variable attenuators finely adjust laser intensity to simulate different lighting conditions, supporting tests on material light response and optical device performance.Medical and Laser Applications:In laser surgery, absorptive attenuators reduce laser power to a safe range, avoiding tissue damage caused by excessive energy and ensuring treatment safety.Industry and Laser Processing:In high-power laser processing (such as cutting and welding), high damage threshold attenuators control laser energy to meet the processing needs of different materials, preventing equipment overload.Optical Device Production and Testing:During the production of optical devices (such as lasers and optical amplifiers), attenuators simulate different light intensity environments to test device stability and tolerance.Product Parameters CharacteristicsBrandThickness (mm) A[2856k] D65 Chemical Stability ND α×10-7(oC) Tg(oC) Ts(oC) S xyYxyYDADWAT000.5 531.527654695822.46AT021 531.514654695822.41AT 220.4470.3961.10.3060.315 531.509654695822.43AT52 541.505654695822.42AT1020.4340.4029.00.2970.314 131.526654695822.52AT2520.4420.40825.70.3080.32725.4531.502654695822.41AT302 131.523654695822.52AT5020.4440.40845.70.3100.32945.0531.502654695822.41AT652 131.521654695822.52AT7020. 4990.41070.20.3160.38568.7531.5026546 Technical RequirementsBrandThickness (mm)V(Mired)QZ(%)StandardToleranceAT000.52.01.0~4.0≤4.0AT0211.50.5~3.0≤3.0AT222.01.0~3.0≤3.0AT525.01.0~9.0≤5.0AT10210.06.0~15.0≤5.0AT2522518.0~32.0≤6.0AT3023023.0~37.0≤10.0AT5025041.0~59.0≤8.0AT6526558.0~72.0≤6.0AT7 027063.0~77.0≤7.0Bubble, Stripe, and Stress GradesBrandBubblesStripesStressAT00C-B43AT02C-B43AT2C-B43AT5C-B43AT10C-B43AT25C-B43AT30C-B43AT50C-B3C3AT65C-B3C3AT70C-B3C3
