We can prepare a quote using just the three basic criteria of:

• ● Desired retardance (quarter wave, half wave, etc.)

• ● Wavelength of operation

• ● Clear aperture (area and shape over which the design criteria apply)

However, additional factors which, while not essential to the preparation of your quote, may be beneficial in considering your application and also in helping us target your requirement more specifically.

Please take a quick look down this list and add any information you would like us to consider.
