This SP750 shortpass filter is designed to transmit shorter wavelengths while reducing longer-wavelength infrared light. It is suitable for imaging, sensing, and optical inspection systems where shorter-wavelength signal needs to be separated from longer-wavelength background using broadband illumination or wavelength-centered signal detection setups. It helps reduce long-wavelength interference, protect detectors from unwanted infrared light, and improve signal clarity in shorter-wavelength measurements.

Key specifications:

  • Wavelength / main spec: 750 nm cut-off wavelength
  • Bandwidth / transition spec: See specification table for transition characteristics
  • Transmission / blocking: T >95%; OD6 blocking from 760-1200 nm
  • Format / custom option: Available in Dia 12.5mm to dia 25mm (mounted/unmounted), 60x60mm(unmounted); Custom sizes and mounting options available on request
SP750 Shortpass Filter - Multiphoton (Two-Photon) Microscopy

SP750 Shortpass Filter - Multiphoton (Two-Photon) Microscopy

Multiphoton (Two-Photon) Microscopy

This specification is a classic match for an Emission Filter in Multiphoton Microscopy.

  • How it works: In multiphoton microscopy, you use a high-power infrared laser to penetrate deep into biological tissue. This laser excites fluorescent dyes in the sample, which then emit visible light.
  • The Filter's Job: You need to detect the faint visible glow (fluorescence) while blocking the blindingly bright infrared laser that acts as the excitation source. Because the excitation laser is so powerful, you need an OD6 rating (1,000,000:1 rejection ratio) to ensure none of that laser light reaches your sensitive detector (PMT or Camera).

Request Light Source:

  • For Multiphoton (Two-Photon) Microscopy, the light source is the most critical component of the entire system. Because this technique relies on "non-linear" optics (two photons hitting a molecule at the exact same femtosecond), you cannot use standard continuous lamps or diode lasers. You must use Ultrafast Pulsed Lasers.

SP750 Shortpass Filter - Raman Spectroscopy (Anti-Stokes)

SP750 Shortpass Filter - Raman Spectroscopy (Anti-Stokes)

Raman Spectroscopy (Anti-Stokes)

It can be used to block a 785nm or 830nm Raman laser line while analyzing "Anti-Stokes" scattering (signals shifted to shorter wavelengths/higher energy than the laser).

Recommended Light Sources

The "light source" you use depends on which side of the filter you are on.

A. Sources the filter is designed to BLOCK (Excitation Sources)

These are the sources you would use to illuminate or excite your sample. The filter prevents this light from blinding the detector.

  • Ti:Sapphire Lasers (Tunable): The most common source for multiphoton microscopy, usually tuned between 760nm and 1000nm.
  • Nd:YAG Lasers: Operating at 1064nm. This filter blocks this wavelength completely.
  • NIR Diode Lasers: Common wavelengths like 785nm, 808nm, 830nm, or 980nm.

B. Sources the filter is designed to TRANSMIT (Signal Sources)

These are the sources (or signals) that will pass through the filter to be seen by your eye or camera.

  • Fluorophores (Fluorescent Dyes):DAPI / Hoechst (Blue emission ~460nm)GFP / FITC (Green emission ~510nm)RFP / mCherry / Texas Red (Red emission ~610nm)Note: It will transmit Cy5 (emission ~670nm) but will cut off dyes that emit deeper into the NIR (like Cy7).
  • Broadband White Light (Halogen/Xenon): If used in a projection or illumination system, this filter effectively "cleans" the beam, removing the heat (IR) and transmitting "cool" visible light.
