Specification Notes

Depth-of-field (DoF) - achievable DoF will vary according to:
- Eye accommodation capability
- Working distance; longer working distance = longer DoF
Field Size (FS) - achievable FS will vary according to:
- How close the ocular is to the eye
- Working Distance; longer working distance = more FS

Interchangeable Working Distance Caps

You can adjust the working distance on your SurgiTel Compact Prism Telescopes by
changing the working distance caps at the end of the telescope oculars.
If looking to change your current working distance caps, please inquire with Customer Service.

Eye Prescriptions

If you have any kind of eye prescription or correction (e.g. distance, reading, "drugstore readers"), this must be used with your telescopes in order to see through them correctly and needs to be submitted with your order.
Prescriptions can only be upgraded by SurgiTel.
