Sapphire crystal K9 glass light guide block

The light intensity can be reduced by using the absorption characteristics of the material, which can be made into sheets and placed on the light road. The amount of light through the attenuation sheet is related to the type of material, and also to the thickness of the material. If THE STANDARD transmittance ON the attenuator is 0.02, it means that THE light passing through the ATTENUator will pass through only 2% of the original light intensity. A beam of light contains different wavelengths of light. The meaning of a neutral attenuator is that light passes through such an attenuator, and the different wavelengths are attenuated in the same proportion.

When used in laser instruments

When the laser output power is too high, the output object cannot bear such high heat. At this time, adding an attenuation piece can effectively reduce the output power, so as to control the power within the range that the object can bear. The customer can choose the required attenuation degree independently, and our company will provide the corresponding attenuation piece.

For UAV aerial photography and photography filters

Our is reflective ND mirror adopts imported optical glass surface of optical coating processing, can ensure a smooth spectral response for light, and not easy ageing under general conditions, which can realize from ultraviolet to near infrared range of homogeneous attenuation, double-sided coating film no glance, one side to add waterproof membrane plating, ensure the quality of the wet conditions will not affect the shooting. It has the characteristics of both colored glass ND mirror and ordinary coated ND mirror. In the case of low reflection characteristics of colored glass, the attenuation value can be flexibly customized in the range of OD0.1 to OD5. Conventional size: 46mm, 52mm, 55mm, 58mm, 67mm, 72mm, 77mm, 82mm, can be customized at any time according to customer requirements.
