One of our High Transmission (HT) precision range of filters, this 1.25"" Luminance & Clear filter is sure to impress on performance, quality and price. Each filter comes with its own individual data sheet of performance - guaranteed! This is the equivalent to the MC-Clear filter and is used for the same purposes which are to maintain the parfocal characteristics if using other HT filters and is required by your imaging system, to keep out unwanted reflections and for dust protection. It has UV and IR blocking characteristics. The filter is constructed to the same exacting standards as the other filters in the HT series and its multicoating cuts out unwanted reflections without changing the natural colours. Our Luminance & Clear filter is excellent for keeping dust at bay from your optical sensors. It also has the same scratch resistance and is constructed on the same high quality optical substrate.
