Glass Expert quickly and efficiently simulates the process an experienced optical engineer would follow in performing glass selection. To start, pick the elements in your lens system you want Glass Expert to examine. Starting materials for the selected elements may be real or fictitious. Glass Expert will replace all fictitious glasses with real glass types.
Then, choose your criteria for filtering the glass selection. For example:
- Cost. You can enter an upper limit for any individual element in the system. This allows you to specify that an expensive glass might be acceptable for a small element, but not for a large one.
- Weight. You can enter an acceptable upper limit for the weight of the system. Prospective glass types are then restricted to those that are estimated to keep the weight of the system below the specified threshold.
- Bulk absorption. You can enter an acceptable lower limit for transmission at the extreme ends of the spectrum. Glass types considered for the element are then restricted to those that would keep the transmission of the system above the specified threshold.
In addition, you can specify one or more glass catalogs (including IR materials and user-defined catalogs) for Glass Expert to choose from, and filter glasses according to refractive index and stain resistance.
