O16412 600 nm longpass filter

600 nm nominal-edge longpass filter (O16412)

O16412 is a longpass filter. A high-transmission region is shown at approximately 607-780 nm. Consider it when you need to pass longer wavelengths and reduce shorter-wavelength light within the measured range.

Optical performance

• Measured wavelength range: 380-780 nm. Performance outside this measured interval is not established by this curve.
• Selected regions at or above 80% transmission: 607-780 nm. Approximate measured intervals.
• Selected regions at or below 5% transmission: 380-573 nm. Measured sample intervals; confirm the required blocking for your order.
• Peak transmission: Approximately 95.2% at 702 nm. Peak wavelength is not the same as a defined centre wavelength.
• Measured edge at 50% transmission: Approximately 598.6 nm. Interpolated absolute-transmission crossing, checked against the factory summary.
• Customization: We can customize stock and sample-book designs. Tell us the wavelength response, size and operating conditions you need.

These values come from the measured samples and help you choose a starting design. We will agree the final specification for your order. Custom versions have their own specifications and measured curves.

Applications to consider

• Illuminated machine vision: Consider a source operating inside 607-780 nm, with unwanted background on the shorter-wavelength side. Check the signal and background spectra together.
• Broad spectral collection: Evaluate passing a range of longer wavelengths into a detector. Confirm its upper sensitivity limit because a longpass edge does not provide an upper band limit.
• Fluorescence instrument development: Consider an emission-side longpass only when the excitation wavelength falls in a sufficiently attenuated region. Specify rejection at that exact wavelength and any additional blocking optics.

Choosing this filter

• Check the full wavelength range of your light source, the wavelengths your detector responds to, and how much unwanted light you need to block. Use the full curve when choosing a filter; the product code and peak do not tell the whole story.
• Tell us the angle at which light reaches the filter and whether the beam is parallel or converging. For demanding rejection or high-power use, confirm the required blocking and power-handling specifications.

Custom options

Start with this stock or sample-book design, then tell us what you need to change. We can discuss the wavelength bands, transmission, blocking, angle, glass material, size and operating conditions with you, and agree a specification for your custom filter.
