Superior Resolution for Distance Diagnostics

The UT-Z044 Telephoto Lens delivers the highest spatial resolution in the standard UTi760X lens lineup at 0.33 mrad, enabling accurate temperature measurement of small components at distances where other lenses would lack sufficient detail. This exceptional resolution allows you to identify individual electrical connections, bearing housings, transformer bushings, and other critical components from safe working distances. The 36mm focal length provides natural 2x magnification compared to the standard lens, effectively bringing distant targets closer while maintaining the UTi760X's measurement accuracy specifications.

The narrow 12° x 9.6° field of view concentrates the UTi760X's 640x512 detector array on smaller target areas, maximizing pixel density for detailed component analysis. This focused perspective eliminates extraneous background information, making thermal anomalies easier to identify and document. The F/1.0 aperture ensures the lens gathers maximum thermal radiation even from distant targets, maintaining the camera's exceptional 35mK thermal sensitivity for reliable detection of subtle temperature differences.

Understanding Telephoto Performance and Resolution

The UT-Z044's narrow 12° x 9.6° field of view concentrates imaging power on distant targets. At typical inspection distances, the coverage areas are:

• At 5m (16.4 ft): Captures approximately 1.05m x 0.84m (41.3" x 33.1")
• At 10m (32.8 ft): Captures approximately 2.10m x 1.69m (82.7" x 66.5")
• At 20m (65.6 ft): Captures approximately 4.20m x 3.37m (165" x 133")
• At 30m (98.4 ft): Captures approximately 6.30m x 5.06m (248" x 199")

The exceptional 0.33 mrad spatial resolution provides the finest detail available in standard UTi760X lenses. With the 640x512 detector:

• At 5m (16.4 ft): Each pixel represents approximately 1.65mm (0.065")
• At 10m (32.8 ft): Each pixel represents approximately 3.3mm (0.13")
• At 20m (65.6 ft): Each pixel represents approximately 6.6mm (0.26")
• At 30m (98.4 ft): Each pixel represents approximately 9.9mm (0.39")

This superior resolution enables accurate temperature measurement of electrical connections, mechanical components, and building elements at extended distances where standard lenses would lack sufficient detail for reliable diagnostics.

Lens Comparison Guide

Frequently Asked Questions

When should I choose the Telephoto Lens instead of the Standard Lens?

Choose the UT-Z044 Telephoto Lens when working with elevated equipment, hazardous systems requiring safe standoff distances, or any situation where you need detailed component-level inspection beyond the effective range of the standard lens. It's essential for overhead power lines, rooftop equipment, high-voltage systems, tall building facades, and industrial installations where physical access is restricted. The telephoto lens is also valuable when you need maximum spatial resolution for small component temperature measurement at medium distances of 5-30 meters (16-98 feet).

What are the safety advantages of using a telephoto lens for electrical inspections?

The UT-Z044 enables safe inspection of energized electrical equipment from distances that maintain proper arc flash boundaries and electrical safety clearances. You can perform detailed thermal assessment of high-voltage connections, transformer bushings, overhead lines, and substation equipment while maintaining NFPA 70E compliance and OSHA electrical safety standards. This capability protects technicians from electrical hazards while still providing the thermal detail needed for accurate predictive maintenance and failure prevention. The telephoto perspective also keeps inspectors away from elevated work hazards when assessing overhead systems.

How does the spatial resolution compare to using digital zoom with the standard lens?

The UT-Z044's optical telephoto design delivers true 0.33 mrad spatial resolution using the full 640x512 detector array, providing genuine detail that cannot be replicated with digital zoom. Digital zoom simply enlarges existing pixels without adding real information, degrading image quality and measurement accuracy. The telephoto lens doubles the effective magnification while maintaining full thermal sensitivity and measurement precision, ensuring you can accurately measure small targets at distance. For professional diagnostics requiring reliable temperature data, optical telephoto performance is essential.

Can I use the Telephoto Lens for general inspection work?

Yes, while optimized for distance work, the UT-Z044 can serve as a general-purpose lens when you need maximum detail resolution. Its 1m (3.3 ft) minimum focus distance allows use at moderate working distances, and the narrow field of view helps isolate specific components or equipment sections for detailed analysis. Many professionals use the telephoto lens for precision electrical connection assessment, small mechanical component monitoring, and situations where eliminating background clutter improves thermal anomaly identification. However, for close-quarters work or broad area surveys, the standard or wide-angle lenses are more efficient.

What is the warranty period for the UT-Z044 Telephoto Lens?

UNI-T provides a 1-year warranty on the UT-Z044 Telephoto Lens, covering manufacturing defects and component failures under normal use conditions. This warranty ensures your investment in professional thermal imaging accessories is protected.

Why Choose the UT-Z044 Telephoto Lens?
