Applications
Aesthetic Instrument Device , Police multiband detection equipment , A flashlight. , Stage light. , Face-recognition timers. , Optical instruments , Optical Fiber Lighting , Gold halogen lamps insulation tablets , Cold Light Shower 。 This one. 490 Shortwaves through their own specific optical indicators , Causes an Ordinary Light Beam to Pass Through Gas Optical Filter Then only the blue spectrum will pass. , And by this optical app , Like what? : Police multiband detection. , One of the optical devices will be used. 。
Key Features
This product is short wave through. 490nm Optical Filter , Because the light that passes through is blue. , So it's called... Blue Filter 。 And the traditional color. Optical Glass Optical Filter Compare , My company produces shortwaves. Longpass Filter is Cutoff Large steepness 、 Transmittance High and high background light density. , And it's the same as tradition. Optical Glass The way you do it is completely different. , When the angle of the entry changes ( From 0 Turn to the big angle. ), Characteristics Cutoff Wavelength It's moving in short wave direction. 。 This function can be applied to the system fine-tuning. , And get what you need. Wavelength 。
