  • BP970-10 Bandpass Filter - Moisture & Water Content Measurement

    BP970-10 Bandpass Filter - Moisture & Water Content Measurement

    Moisture & Water Content Measurement

    • How it works: Water absorbs light at 970 nm. By measuring how much 970 nm light is reflected or transmitted through a sample, you can calculate its moisture content. (More water = Less signal).
    • Use Cases: Agriculture (monitoring vegetation water stress), food processing (measuring moisture in grains or baked goods), and paper manufacturing.

    Recommended Light Sources

    • Tungsten-Halogen Lamp (Broadband Source): These lamps are extremely stable over time, which is critical for quantitative measurements (calculating exact water %). They also allow you to add a second filter (e.g., at 800 nm) later if you need a "reference wavelength" to correct for surface scattering.
    • High-Power 970 nm LED (Narrowband Source): Low power consumption, minimal heat generation (preventing the sample from drying out during measurement), and very long lifespan.

  • BP970-10 Bandpass Filter - NIR Machine Vision & Inspection

    BP970-10 Bandpass Filter - NIR Machine Vision & Inspection

    NIR Machine Vision & Inspection

    • How it works: Using this filter allows a camera to "blind" itself to sunlight and room lighting, seeing only the 970 nm light source.
    • Use Cases: Optical sorting, quality control in factories, or night-time surveillance where invisible IR illumination is required.

    Recommended Light Sources

    • High-Power NIR LEDs (970 nm)
    1. Spectral Match: Unlike standard "white" lights that waste energy across the spectrum, these LEDs emit all their power right at 970 nm. The BP970-10 filter passes this light through while blocking sunlight and factory lights.
    2. Strobing Capability: In high-speed sorting, LEDs can be pulsed (strobed) to freeze motion and provide bursts of intensity that overpower ambient light.
    3. Invisibility: The light is invisible to the human eye, avoiding operator distraction or light pollution in dark environments.

    • NIR Laser Diodes (970 nm): If you need to measure the shape or volume of an object (not just take a picture), a laser projects a precise line or grid. The filter ensures the camera sees only that laser line, even in bright conditions.

Fequently Asked Questions

Different Types of Filter Mountings

Unmounted:

  • a bare glass optical filter

Mounted:

  • Smooth Mount for protection of the optics. No thread is there on the mount.

Metric Mount:

  • Start with M as prefix, usually seens as M25.5x0.5mm. Mostly used as camera filters

Imperial Mount:

  • Start with SM as prefix, usually seen SM1, SM05 etc... Mostly used in Optical system. (You will have a SM external thread to connecting to other objects)

C-Mount:

  • Very frequently used mounting. C-Mount is 1‘’-32TPI. And it is not the same thing as SM1, or M25.5x0.5mm.

What are the Thickness of the Optical Filters?

For Unmounted Optics:

  • 0.5mm
  • 1.1mm
  • 2.0mm

*Most of our optics are coming with 1.1mm and 2.0mm
