Product Description Product Description Introduction to Purple FiltersA purple filter is an optical component that selectively transmits or reflects light within a specific wavelength range. It is primarily designed to allow purple light (with a wavelength range of approximately 380-450 nm) to pass through while suppressing or blocking light of other colors.Core Characteristics:Light Transmission Properties:Typically covers the purple light wavelength range (380-450 nm), with possible slight extensions into adjacent blue or ultraviolet regions (specific ranges vary by model).Parameters such as transmittance and cutoff depth depend on the material and coating process used.Types and Materials:Absorptive Filters: These filters absorb light of other wavelengths using dyes or glass, offering lower costs but potentially generating heat.Interference Filters: Based on the principle of thin-film interference, these filters provide high precision and stable performance, often used in precision instruments.Material Options: Optical glass (heat-resistant), resin (lightweight and easy to process), quartz (suitable for ultraviolet light), etc.Main Applications:Photography and VideographyScientific ExperimentsIndustrial InspectionDisplays and LightingProduct Parameters Characteristics of Ultraviolet Transmitting and Vis ible Absorbing Glass:BrandThicknessA[2856k]D65Chemical StabilityNDa × 10^-7 V/oCTg (oC)Ts (oC)S(X)(y)(Y)(X)(y)(Y)(DA)(DW) AT110.7340.2660.10.7260.2620441.557945295882.87AT210.5320.1710.90.2310.0320.4221.52975155892.65AT320.7110.2560.30.53 80.1760.1231.526855276162.63Technical Requirements for Ultraviolet Transmitting and Visible Absorbing Glass:BrandThickness (mm)254 (nm)280 (nm)313 (nm)334 (nm)365 (nm)405 (nm)700 (nm)AT11 ≥50.0281.0 ≤1.0S30.0AT21 ≥38.0 ≥80.0≤8.0≤14.0AT32≥50.0 ≥86.0 ≤28.8S64.6Bubble, Stripe, and Stress Levels for Ultraviolet Transmitting and Visible Absorbing Glass:BrandBubblesStripesStressAT1C44AT2C43AT3C44Detailed Photos
