Gramm per 1,000 pcs.Made from B270

Introduction

Half ball lenses are specially designed for the use in the field of LEDlighting. They are intended for the production of very large quantities.Prices comparable with the price of plastic lenses are combined with allthe very useful characteristics of three different glass types:

High surface qualityScratch-proof surfaceHigh or very high refraction indexHeat resistant up till more than 300°C (572°F)

How to find the right glass type:In most cases, B270 will be the best choice. It is a very highquality optical glass at a very good price. Its thermalexpansion rate lies within a good range, but not as good asthat of Borosilicate glass.If you need a very high refraction index, F2 will be a goodchoice. It is a special optical glass at a much higher priceas B270 or Borosilicate glass, and is thus not a standard glassin stock.If you require a very low thermal expansion rate combinedwith a mid-range refraction index, Borosilicate glass will be the firstchoice. The price of this glass lies between that of B270 and F2. Half balllenses of Borosilicate glass are not available from stock.

High-quality optical glass, by Schott,with a high refraction index.The expansion index is a little bit betterthen the index of B270, but the price ofF2 is much higher.So, F2 is the best glass where a muchhigher refraction index than B270 is amust.

Blank moulding allows to producenearly any kind of geometry and combinations of lenses thatcan be created by optics developers and system designers.

MOULDED OPTICS GMBH

The geometry of the optically effective surface is notrestricted to radii; blank moulding allows to producelenses with aspherical surfaces.There are many applications in which aspheric lenses willimprove the performance of technical and opticalsystems.

Many applications need lenses in flye-eye-array.

Blank moulding allows toproduce just the right arrayyou need. This helps to saveassembly costs.P lease note that the
