IR Cut / Pass Filter (Infrared filter, Day and Night IR)
(The following spec. is for example, we can design and produce customer need. Please contact us)
(check substrate type, thickness, dimension, shap.)
IR Pass Filter (Infrared pass, visible light cut, also named "Cold Mirror")
Apply:
The IR pass filter (Infrared pass filters) that operates over a very wide temperature range to reflect the entire visible light spectrum while very efficiently transmitting
infrared
wavelengths. So that can increase the temperature of bathroom.
IR filter Pass 700
400~650nm Tabs<3%
730~1050nm
Tabs >90%
T=50% @ 700 +/-10nm

IR filter Pass 850
420~680nm Tabs>97%
730~1050nm
Tabs >90%
T=50% @ 850+/-10nm

IR Cut Filter (Infrared cut, visible light pass, also named "Hot Mirror" / IR blocking)
Apply:
1. The IR cut filter often employed to protect optical systems by reflection heat back into the light source.
2. The IR cut filter are crucial to CCD/CMOS of digital camera lens which are sensitive to infrared wavelengths,
... this filter could adjust the performance of
sensor to human eye.
IR filter Cut 650
T50% @ 640~660
Tabs>90% @420~630
Tabs<3% @680~1100

IR filter Cut 710
T50% @ 700~720
Tabs>90% @420~690
Tabs<3% @750~1100

Day / Night IR Cut Filter (Day and Night Infra Red Cut / blocking filter)
Apply:
Day / Night IR cut filter often employed to minitor system. It could adjust the performance of CCD/CMOS in the day time. And use the 800~1000
infrared wavelengths to capture the image in the night.
ETAFILM own unique competitiveness in Day and night IR filter.
ETAFILM is the ace IR filter coating producer in Taiwan. Share 90% of day and night IR filter of Taiwan market.
