| |||
| 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. | ||

|
|
| ||
| 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. | ||
| |||
Incidence

|
|
| ||
| Incidence: | The angle the incident light for the filter to operate correctly. | ||
| Your choices are... | |||
| 0° Incidence | Filter operates with incoming light at 0° incidence. | ||
| 45° Incidence | Filter operates with incoming light at 45° incidence. | ||
| 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. | ||

| ||
| 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. | ||
