The short-pass filter is a separation filter that can transmit light on the short wave side and cut off light on the long waveside. Excellent performance, in the transmission band, the transmittance exceeds 90%. Can be used for biological imaging or flow cytometry.
The long-pass filter is a separation filter that can transmit light on the long wave side and cut off light on the short wave side. Excellent performance, the light transmittance exceeds 98% in the light transmission band. Widely used in beauty equipment,such as hair removal and beauty equipment, etc.
The bandpass filter allows the optical signal to pass through in a specific band, while the optical signals on both sides of the band are blocked. However, the bandpass of the bandpass filter is relatively wide, and the half bandwidth is generally 40nm or more. The narrow-band filter is an optical lens that suppresses the light source, the sensor, and the natural light and separates a specific monochromatic spectrum. The narrow-band filter is a filter that cuts off the interference light and transmits the characteristic wavelength
Application
