Help with Spectral Filters specifications:

Wavelength Range


	Transmission Range:		The area of the spectrum where the filter transmits.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

	Rejection Range:		The area of the spectrum where the filter does not transmit.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Filter Geometry


	Filter Shape:		Filters can either come round, square, or rectangular.
	Your choices are...
	Circular		The filter is circular.
	Square		The filter is square-shaped.
	Rectangular		The filter is rectangle-shaped.
	Other		Other unlisted, specialty, or proprietary filter shape.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Diameter, Square Side, or Rectangular Length:		If the filter is circular, the diameter. If the filter is square, the length of a side. If the filter is rectangular, the length of its largest side.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Rectangular Width:		If the filter is rectangular, the length of its shorter side.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Thickness:		The thickness of the filter.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Filter Surface Quality


			Surface quality of the filter glass.
	Your choices are...
	10-5 Scratch / Dig		A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 10 / 5 indicates the average diameter of the digs to be .05 mm and the average length of a scratch is .10 mm.
	20-10 Scratch / Dig		A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 20 / 10 indicates the average diameter of the digs to be .10 mm and the average length of a scratch is .20 mm.
	40-20 Scratch / Dig		A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 40 / 20 indicates the average diameter of the digs to be .20 mm and the average length of a scratch is .40 mm.
	60-40 Scratch / Dig		A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 60 / 40 indicates the average diameter of the digs to be .40 mm and the average length of a scratch is .60 mm.
	80-50 Scratch / Dig		A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 80 / 50 indicates the average diameter of the digs to be .50 mm and the average length of a scratch is .80 mm.
	Other		Any other scratch / dig surface quality rating.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
