The full power Oslon Black T-20 IR conversions were a necessary creation for rear add-on NVD's that have to drag an illuminated image through a day scopes several lenses that have the wrong wavelength coatings - then a tiny exit pupil - all before it gets to the camera lens - then the sensor.
The photon is too responsive to very low light levels for your own good if you continue to throw the huge amounts of light out front needed for those less efficient rear add-on type night vision devices. The extremely low lux rated camera used in the Photon is working the way it was designed to work with one decent lens assembly in front of it, probably with IR wavelength anti reflective coatings on -
Like any decent camera, the light reaching the sensor often needs to be reduced so that it doesn't overpower the image... but the Photon is not equipped with an iris to facilitate that. Moderate IR levels coupled with a moderate iris of 25mm~27mm is more sensible.
If you are going to unnecessarily bang loads of light out for a Photon you will need to reduce the amount of light hitting the sensor by a very substantial amount. Salmo has had to block off excessive light which is completely unnecessary for the standard Photons maximum 200 yardish practical range with an otherwise unnecessarily light reducing iris.
I can't be the only guy who thinks it seems silly to use excessive light for sometimes light shy quarry just because you can - then restrict loads of it from getting to the camera.
