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 be upgraded by either SurgiTel or your local optometrist.
