TUBE SELECTION (IN STOCK INVENTORY)
For our in stock units, each tube is individually listed with its measured performance values so you can see exactly what you’re getting. These include center resolution, SNR, EBI, halo, and FOM.
(LP) Center Resolution
Similar to screen resolution the higher the number, the finer the detail. For helmet mounted use, resolution above 64 LP is generally indistinguishable to the naked eye.
SNR (Signal to Noise Ratio)
This represents how well the tube performs in low light conditions. Higher SNR means a cleaner image with less noise. This is typically the most important specification when evaluating low light performance.
EBI (Equivalent Background Illumination)
EBI indicates how dark an environment can be before the tube begins to lose image quality. Lower values are better. For most real world use, anything under 2.5 performs very well.
Halo
Halo measures the amount of bloom around bright light sources. Lower halo values result in tighter, more controlled light bloom.
FOM (Figure of Merit)
FOM is calculated by multiplying center resolution by SNR. While commonly referenced, it’s best used as a general reference rather than a deciding factor. Looking at resolution and SNR individually provides a clearer picture of real-world performance.
PHOTOS THROUGH THE TUBE
Photos are provided to show cosmetic characteristics such as spotting or shading. Very small spots, including those under 0.003 microns or located near the edge of Zone 3, may not be visible in photos. If you are looking for an exceptionally clean tube, we recommend contacting us prior to purchase. Images are for reference only and are not representative of actual brightness, image quality, or color hues, which may vary due to camera settings and lighting conditions.
