First light - Import export

Within medicine the use of polarised light was first introduced back in the70’s; since then it has come leaps and bounds. How it has been used to help with imaging skin pathologies, when the skin is illuminated by linearly polarised light it causes backscattering of the superficial layers of the skin where cancer often arises. This superficial backscattered light can be distinguished from the diffused reflected light when using a detector. Polarised Beam-Splitter Cubes, Sheet Linear Polarisers, and Sheet Circular Polarisers are often used within detection devices for this type of skin pathology imaging. Knight Optical hold a large inventory of Polarisers for use within Skin Cancer Detection devices. •We stock large sheets up to 1270x480mm in some cases; we can cut these into special shapes at short notice. •Mounting options are also available. •Special Glass laminating to CAB polarisers •Special AR coatings.

Dim-to-warm is a LED lighting which emulates a halogen lamp when dimmed, so when you dim it down (reduce its brightness) the colour temperature changes to a warmer colour. This special LED lighting, despite the classic LED that when dimmed changes only the brightness, changes the colour from 3000K to 1800K. It’s perfect for decorative luminaries, and can be used in hotels, restaurants and residential projects. Perfect to create the right atmosphere when needed, just at a flick of the control unit. How it works? We are used to LED lighting dimming but keeping the same colour rate, just changing the brightness. On the contrary, a dim-to-warm LED lighting is made by two different areas, one with a cooler colour temperature and another with a very warm colour temperature. When dimming the lighting, it will first interact with the cooler area, and once completely dimmed it will start working on the warmer area.
