Custom IR Filter Glass HWB1 HWB4 HWB3 Lens

Custom Optical IR Filter Glass HWB1 HWB4 HWB3 Lens  Introduction to HWB-Series Infrared (IR) Absorptive Glass Filters HWB1, HWB3, and HWB4 are types of infrared-transmitting glass filters that operate on the principle of absorption. These filters are manufactured by incorporating specific metal oxides and dopants (most notably Copper Oxide - CuO) into the glass melt. This composition gives them the unique property of being opaque to visible light while highly transparent to infrared radiation.   Specification: They belong to a classic family of optical glasses designed for IR transmission. Their primary function is to completely block ultraviolet (UV) and the entire visible spectrum (violet, blue, green, yellow, orange, red) and to transmit only near-infrared (NIR) light.   Key Characteristics:   · Type: Absorption Filter · Material: Copper-doped Optical Glass · Primary Function: To transmit near-infrared (IR) light while completely blocking visible light. · Visual Appearance: The…
