Warming color-correction filter (CTO-025)
CTO-025 is listed as a warming color-correction filter. The supplied factory files contain different curves for this ID. Ask KUPO to confirm which version matches your sample or order before choosing the wavelength and transmission specifications.
Optical performance
- Source selection: Multiple factory versions are available. The comparison chart presents them separately; no numerical version is approved here.
- 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
- Application development: Use the available curves to discuss the required source, detector and wavelength response with KUPO. Confirm the product version before finalizing the application.
Choosing this filter
- Confirm which factory version matches the sample you already have.
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 CTO-025
Which CTO-025 curve should I use?
The factory files contain two different versions under this reference. Neither has been selected as the order specification. Send us your sample-book edition, an existing sample or the specification you need so we can identify the matching version.
Can I still use CTO-025 as a starting point for a warming filter?
Yes, as a discussion reference. The two curves are shown separately above so you can explain which response you need. Confirm the version before comparing transmission values or choosing dimensions for an order.
Discuss this filter with KUPO - include the product reference, source wavelength, working angle and required dimensions.
