This LP510 longpass filter is designed to transmit wavelengths longer than the cut-on region while reducing shorter-wavelength visible light. It is suitable for fluorescence imaging, optical inspection, and visible-band optical measurement systems where longer-wavelength signal needs to be separated from visible excitation or shorter-wavelength background. It helps separate longer-wavelength emission from shorter-wavelength excitation and reduce visible background interference.

Key specifications:

  • Wavelength / main spec: 510 nm cut-on wavelength
  • Bandwidth / transition spec: See specification table for transition characteristics
  • Transmission / blocking: T>85% from 520-1200 nm ;  OD5 from 200-500 nm
  • Format / custom option: Available in 25.4 mm diameter and 60x60mm, mounting options
LP510 Longpass Filter - Fluorescence Imaging and Microscopy

LP510 Longpass Filter - Fluorescence Imaging and Microscopy

Fluorescence Imaging and Microscopy

In this application, scientists shine a blue or UV light on a sample (like cells, plants, or minerals) to make it glow in different colors (fluoresce). The LP510 filter acts like a pair of protective sunglasses for the camera lens. It strongly blocks the bright blue/UV "shining" light (from 200-500nm) so it doesn't blind the camera, while letting the much fainter green, red, or infrared "glowing" light (520-1200nm) pass through to be captured clearly.

Recommended light source:

  • Blue LED (e.g., 470nm or 488nm): It is excellent for "waking up" or exciting many common fluorescent dyes. Because its wavelength is strictly under 500nm, the filter will completely block it from ruining the final image.
  • UV Light or UV LED (under 400nm): Great for examining forensic evidence, counterfeit money, or specific minerals. The filter easily blocks the harsh UV glare while letting the resulting colorful glow pass through to the camera.

LP510 Longpass Filter - Outdoor Photography and Drone Mapping

Outdoor Photography and Drone Mapping

In the earth's atmosphere, blue and UV light scatter everywhere, creating a visual "haze" or fogginess over long distances. This filter acts as a "haze-cutter" for specialized photography or aerial drones. By blocking the scattered blue light and letting only the direct green, red, and infrared light through, it creates incredibly sharp, high-contrast images of landscapes.

Recommended light source:

  • Natural Sunlight: Sunlight provides a massive, full spectrum of light. Using the filter outdoors removes the scattered blue sky haze and invisible UV rays, resulting in crisp, detailed photos of the ground.
  • Infrared (IR) Illuminators: For drones or outdoor security cameras working in low light, these invisible lights provide illumination that perfectly passes through the filter's 520-1200nm opening, allowing the camera to see clearly in the dark without being distracted by streetlights.

Product Faqs

Cut-on / cut-off wavelength

Cut-on / cut-off wavelength is the transition point where an edgepass filter starts or stops transmitting light; in a practical system, it defines which wavelength range is allowed through and which range is reduced or blocked.
Blocking region

Blocking region is the wavelength range where the filter is designed to suppress unwanted light; in a practical system, stronger or wider blocking helps reduce background signal, stray light, and detector interference.
Optical Density (OD)

Blocking depth / optical density (OD) describes how strongly unwanted light is suppressed in the blocking region; for example, OD6 @ 200–1200nm means the filter is designed to block wavelengths from 200–1200nm to about 0.0001% transmission, helping reduce stray light, background signal, and detector overload.
Angle of incidence (AOI)

Angle of incidence (AOI) is the angle at which light hits the filter surface; as AOI increases, interference filters can show a spectral shift, usually moving the transmission or transition wavelength toward shorter wavelengths.
