ETA

ETA autonomous technical fiber and optical endoscope is designed to operate in non-stationary conditions by visually observing images of objects, their individual sections or surface defects, especially those located in hard-to-reach and dimly lit places, operated under moderate conditions climate in the open air and indoors.

Technical characteristics 

- Type of the operating side of the endoscope: flexible.

- Deflection angle of the distal end in one plane within (180 ± 15 °) for Ø = 6.0 mm, Ø = 8.0 mm, Ø = 10.0 mm, (120 ± 15 °) for Ø = 4mm.

- Angle of the field of view of the endoscope (60 ± 5 °). Direction angle of the axis of view is 0 ° or 90 ° (as agreed with the Customer).

- Lower limit of the depth of field is at least 15 mm.

- Diopter adjustment of the eyepiece ± 4 di-opt.

- LED backlight. LED power is at least 1 W.

- Supply voltage of the product is in the range from 4 V to 6 V.

- The permissible number of drafts or gray fibers of a fiber optic bundle in the field of view of the endoscope is not more than 10 pcs.

- Time of continuous operation from one set of fully charged batteries under normal climatic conditions is at least 120 minutes.

NOTE - Continuous operation time is specified for pre-charged rechargeable batteries that have passed at least 3 'charge-discharge' cycles before.

The main functions and adjustments:
