Pulsar Telos XP50 Thermal Imager

The Pulsar Telos XP50 thermal imaging monocular combines a 640 × 480, 17µm sensor with a 50mm f/1.0 lens. Its low published thermal-noise figures make it a useful option when small temperature differences are the main observation challenge, with separate rings for focusing and changing magnification.

Key features

• 640 × 480 thermal sensor with adjustable image processing.
• Variable magnification and Picture-in-Picture viewing.
• Separate focus and zoom rings around the objective lens.
• Selectable colour palettes and viewing adjustments.
• Removable LPS7i rechargeable battery.
• Built-in recording and Stream Vision 2 smartphone connectivity.

Thermal image and field of view

The 640 × 480, 17µm sensor works with a 50mm f/1.0 objective lens. At the 2.5x starting magnification, the horizontal field of view is 12.4°, equivalent to 21.8m at 100m. Digital zoom provides a closer view when you want to inspect an object already located.

The quoted detection range is up to 1,800m. This is a detection figure, not an identification guarantee; usable detail depends on the subject, distance and conditions.

Adjust image processing to the conditions

Sensor NETD is below 18mK, with system NETD below 15mK. Thermal sensitivity helps distinguish small temperature differences between a subject and its surroundings. Sensitivity amplification, brightness and contrast controls let you adjust the image as thermal contrast changes. A smoothing filter provides further adjustment. Choose from 9 thermal colour palettes with supporting current firmware to change the presentation of temperature differences.

Magnification and Picture-in-Picture

Picture-in-Picture displays a magnified inset while retaining the wider scene in the main viewing area. This allows closer examination of an object without filling the entire display with the zoomed view. The standard magnification range is 2.5–10x. With supporting firmware, Zoom Boost extends digital magnification to 2.5–20x.

Focus, zoom and an adaptable design

Separate rings around the objective lens provide direct access to focus and digital magnification. A reversible hand strap and configurable controls let you adapt operation for left- or right-handed use. Menu ordering can be configured to prioritise frequently used functions. The rubber-armoured reinforced housing provides grip and IPX7 waterproof protection. Telos is designed for Pulsar’s hardware upgrade programme; available upgrades depend on the model and current service options.

Rechargeable power

The removable LPS7i rechargeable battery can be exchanged for a separately purchased spare during longer outings. USB-C supports charging and external power. Actual endurance depends on temperature, recording and wireless use. The LPS7i battery also supports wireless charging.

Recording and smartphone connectivity

Capture still photographs and video with sound directly to the 64GB internal memory. Stream Vision 2 connects a compatible Android or iOS smartphone or tablet for live viewing, remote control, downloading files and firmware updates. Dual-band Wi-Fi supports both 2.4GHz and 5GHz connections.

Compare with similar models

Telos XP50 or Telos LRF XP50?

Compare the Pulsar Telos LRF XP50. The LRF version adds a 1,000m laser rangefinder to the same sensor, lens and starting field of view. Choose it when direct distance measurements should be available within the thermal viewer.

Telos XP50 or Telos XL50?

Compare the Pulsar Telos XL50. The XL50 offers a 1024 × 768 sensor, wider 14° view and quoted 2,300m detection range. The XP50’s lower published NETD figures make thermal sensitivity another factor when choosing between them.
