Pulsar delivers the first line of user-upgradable thermal optics with the Telos XP50. This handheld thermal monocular was designed with the ability to be upgraded and enhanced based on the user’s ever-changing needs and preferences. This allows the Telos to be fitted with options such as more powerful optics, a higher resolution sensor and display, more efficient electronics, and additional optical channels. The interface can also be customized by allowing the user to set the order of the items in the device menu, and the User Mode function saves the selected brightness and contrast settings in the device's memory for optimal image quality during the next use of the thermal image quality. Like all of Pulsar’s thermal devices, the Telos XP50 offers exceptional imaging quality and performance. This is thanks to a combination of a high-sensitivity thermal detector, a fast aperture F50/1.0 Germaniun lens, and the advanced Pulsar Image Boost Technology. The thermal detector features a sensitivity of NETD Pulsar Telos XP50 Thermal Monocular PL77493
