HEV Light measuring with SI1133

Hi, can you recommend a filter to measure HEV light with SI1133?

Re: HEV Light measuring with SI1133

The shallow ALS diode of Si1133 peaks in that 400 to 500 nm region but if you want to specifically measure it you need to find a steeply-walled filter that blocks the region from 500 nm to 1100 nm. 


We don't know of one off hand. You should try one of the many custom filter.
