Holosun Paralow Series | Optics Trade Debates

Hello and welcome to another Optics Trade Debates video. We are currently in the process of explaining everything regarding the Holosun brand. Today we’ll focus on the Paralow series, one out of the 4 red dot series that the company has to offer.   Let’s start with some general features of the Paralow series fromContinue reading

Temperature Sensitivity | Glossary

A thermal imaging device enables measuring the temperature of the target without physical contact. Thermal imaging devices can detect the smallest temperature difference of lower than 50 mK (miliKelvin) or 0.05 °C. This is called temperature sensitivity. An easier explanation would be if there are two objects with slightly different temperature (the first object has aContinue reading

Diopter Range | Glossary

Diopter range in optics with one ocular (riflescopes, spotting scopes, NV optics, …)   Diopter range is an adjustment on optical products which can correct the prescription on each of your eyes. That way you can see a sharp image without wearing glasses. The diopter ring is normally located on the eyepiece and by turning it your image appears sharper.Continue reading

Spectral Sensitivity | Glossary

Spectral sensitivity is used to specify the various attributes of the photopigments in the photoreceptor cells in the retina of the eye. Thermal imaging devices operate in different electromagnetic spectrums. The relative efficiency of detection of signals is the spectral sensitivity or spectral response measured in micrometers ( µm ). Typical spectral sensitivity of thermalContinue reading
