Quasar® Plus Sensor Loupe® 7x Magnifier is an improvement to Quasar Sensor Loupe 7x.
The ED Glass (Extra-Low Dispersion) lens in Quasar® Plus Sensor Loupe® 7x Magnifier has been lowered for a better and improved focusing system for sensors placed in deeper cavity. Quasar® Plus Sensor Loupe® 7x Magnifier comes with a 52 mm metal ring to attach filters and close-up lenses for higher contrast and magnification.
For example, using amber filter effectively blocks blue light increasing the contrast and reducing the glare accompanied with sharper image and less strain to the eyes. Blue light blockers are ideal for low vision users. The attachment of UV filters can enhance image clarity and protecting the ED glass lens. The attachment of polarized filter can be helpful in distinguishing stain from dust.
