590 nm nominal-edge shortpass filter (C13116)
C13116 is a shortpass filter. The main high-transmission region is approximately 392-581 nm. Consider it when you need to pass the shorter wavelengths used by your light source or detector. Check the longer-wavelength response as well as the main cut-off.
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: 392-581 nm. Approximate measured intervals.
- Selected regions at or below 5% transmission: 615-780 nm. Measured sample intervals; confirm the required blocking for your order.
- Peak transmission: Approximately 95.3% at 568 nm. Peak wavelength is not the same as a defined centre wavelength.
- Measured edge at 50% transmission: Approximately 589.7 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
- Short-wavelength illuminated inspection: Consider illumination within 392-581 nm when longer-wavelength background interferes with the measurement. Check any secondary transmission against the detector response.
- Illumination-band shaping: Evaluate retaining the shorter-wavelength part of a broadband source. Add a lower spectral limit if unwanted UV or shorter wavelengths must also be removed.
- Fluorescence source conditioning: Consider trimming longer-wavelength output from an excitation source. Confirm signal transmission and rejection at the actual wavelengths rather than assuming a complete fluorescence filter set.
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.

Questions about C13116
Where does C13116 transmit at least 80% in the measured curve?
The measured regions at or above 80% transmission are 392-581 nm. They are measured intervals, not guaranteed passband tolerances. Compare the full curve with the signal wavelengths you need to retain.
How much rejection can I infer from the C13116 measured curve?
The measured regions at or below 5% transmission are 615-780 nm. That threshold is a way to summarize this sample, not a guaranteed blocking specification. For a weak signal beside a bright unwanted wavelength, tell us the actual wavelengths and maximum leakage you can accept.
