Microprism/lenses– Microprism/lenses are small lenses,

generally with less than a millimetre (mm) in diameter.

Pitch– The distance between same point on

repeating patterns

TIR– Total Internal Reflection, The critical

angle is the angle of incidence above which the total internal reflection occurs.



DKIDKI Microprism™ Microprism™

Radius on prismatic structures ≤ 2Micron. (Current competing capabilities is limited to radius ≥ 30-40 Micron.) Small pitch possible due to sharp edges, which produce less chromatic aberrations (Separation of the light relative to wavelength. E.g. Red, green and blue colour exit prism in diverging angle) Film based, Formable to fit customer’s application. Low total thickness of prismatic structure/film reduces internal reflection = improved light control. Low weight (Savings on shipping cost and warehouse sq.m.) Unlimited length No join line due to size limitationsCompetitive pricingDKI offer Optical Design collaboration with customers
