The 39mm Kolari Vision Blue IR/NDVI Pro Lens Filter 39mmfrom Kolari Vision Blue IR/NDVI Pro Lens Filter 39mmworks with full spectrum cameras to transmit both blue and IR, making it ideal for NDVI crop analysis applications. It allows an NDVI to be generated from a single image using the blue and red channels of the image. This filter is also useful for landscape photography, as it produces a similar effect to a 590nm IR filter after a channel swap, right out of the camera. This pro version of the filter features multicoated glass and a slim, knurled brass ring.

A full spectrum modification is required to be made to your camera. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, this filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

Related Questions and Answers

Q: 1. Can this IR filter be used with Rollei Infrared 400 Black and White Negative Film? Is an approximate filter factor available?

A: The Kolari Vision 100 x 100mm Infrared Pro Filter (720nm) can be used with Rollei Infrared 400 Black and White Negative Film. This should have a filter factor of 1 when used with IR film or a sensor modified for IR. The 720nm filter works out to having about as much IR light available as a normal camera has visible light, the easiest to expose for.

Q: 2. Does this filter have to be used with a full spectrum camera?

A: While it may be possible to use the Kolari Vision Pro Gen 3 Infrared Lens Filter (930nm) on an unconverted camera using a long exposure, it is not advised. One would not get good results on a normal camera. The only options for infrared photography when using a normal camera are the 720nm and 850nm filters.
