Quanmin 6.5mm Optical AR-IR CUT filter AR/IR Blocking filter for camera lens M12 etc

Tambien bloquea el UV y no lo pone

Used them to cut IR from my green lasers, to make them safer.

I bought a NOIR camera for the Raspberry Pi (all that was available at the time). Rather than buy a complete new camera I used one of these filters over the lens.I just tacked it on the front of the existing lens with a tiny blob of PVA adhesive applied with the end of a cocktail stick.You can see the difference in the image as a result!!Very very pleased.

Excellent filter to block infrared from sensors and cameras. Note that two filters are provided (not 20). I have attached a photo showing the percentage of incident light transmitted through the filter versus wavelength - it blocks wavelengths larger than about 635nm. The slight mismatch in the spectrum near 460nm is likely due to my spectrometer needing some calibration. These filters should work well with some smaller silicon photodiodes (etc).

アクションカメラにCマウントレンズを取り付ける際に必要な場合があり購入しました。当たり前ですが、必要なレンズに取り付けると色合いが改善します。
