IPL filter
Optical Filters
Uni-lens
Substrate Material: N-BK7, B270, fused silica or other Dimensional Tolerance [General precision; No unit stated in the original table]: ±0.1 Dimensional Tolerance [High Precision; No Unit Marked in the Original Table]: ±0.01
IPL filters are key optical components in intense-pulsed-light machines, blocking ultraviolet wavelengths and transmitting useful wavelengths from 400nm to 1200nm for equipment described as laser equipment in the source. Applications include photorejuvenation, hair removal, vascular and acne treatments, and skin regeneration.

Machine-vision bandpass filter
Optical Filters
Uni-lens
Coating: Antireflection coating Surface Quality: 40/20 Guaranteed peak transmission: >90%
A bandpass filter passes frequencies within a specified range and rejects or attenuates frequencies outside it, selectively transmitting part of the spectrum while rejecting all other wavelengths.
-
Longpass filter
Optical Filters
Uni-lens
Filter Type [LP Series]: Optical interference or colored-glass filter
Long-pass filters serve gas monitoring, temperature sensing, other sensing, thermal imaging, and motion detection. They block shorter wavelengths and transmit longer wavelengths. Blocking can result from reflection, absorption, or both. An antireflection coating on the second surface can improve passband transmission.
