Optical Colored Cut-off Longpass Glass Red Filter 600nm 610nm 630nm 640nm 650nm 670nm 680nm 685nm 700nm 720nm

The colored glass red filter is a cutoff type filter that absorbs the spectrum before a certain wavelength of 600nm/610nm/630nm/640nm/650nm/670nm/680nm/685nm/700nm/720nm. Through the spectrum after it, the center wavelength of the filter remains unchanged for beams of different incidence angles. It is an economical long wave pass filter.

1. The size unit of all optical components is mm.

2. The transmittance of the long wave pass series filter is related to the cutoff wavelength and the actual thickness of the filter. Generally, with thicker thickness, the transmittance will slightly decrease, but the cutoff depth will slightly increase.

3. This type of filter is a cut-off type filter, and the operating temperature should not exceed 200 ° C. (If the operating temperature is between 100° C and 200 ° C, the lens needs to be tempered to improve temperature resistance. This type of filter is not suitable for applications with temperatures exceeding 200 ° C.) It is not suitable for high-power laser applications.

4.There are multiple models in this series, all of which pass through the red light band. The colors of different models are different, and the bands they pass through are also different. Some models have very similar colors, and color should not be used as a basis for selection. Please determine the appropriate band to pass through based on practical applications.
