T1 Driver's periscope
The T1 unity vision periscope has enhanced vision capabilities with its deeper body delivering an increased vertical field of view.
The T1 was designed specifically by Kent Periscopes in response to an urgent operational requirement for a Driver's periscope. This basic design is also available in a narrow version, the T2, intended for installation alongside the T1 in a radial symmetrical array in order to maximise the azimuth field of view.
The T1 has a two prism system with desiccated ballistic gap. Each half of the periscope is collimated to +/- 15' of arc. This enables either half of the Periscope to be replaced in the event of damage, and maintain the original collimation angle tolerance.
The fields of view obtained from this periscope, assuming a nominal eye position of 50mm are as follows:
| Vertical | Horizontal | ||
| Immediate | Cut off | Immediate | Cut off |
| -6° to -24° | +12° to -38° | 78° | 150° |
Please note that the T1 was previously referred to as the KP25000.
Laser protection
A laser filter cassette can be included if required. Housed internally within the centre of the periscope, the cassette is protected from damage and is installed such that the periscope can be upgraded over time in order to respond to changes in threat level.
Typical levels of protection required by our customers include YAG 1064nm (1.064µm) or Ruby 694nm (0.694µm). These levels of protection can be provided alone or on a combined basis. We can also work with our customers to supply laser protection filters that meet other specific wavelength requirements.
