    • An apparatus for recording and/or transmitting optical data or visual images includes a recording medium (100) having a substrate (220) and markable coating (230). The apparatus also includes a recording and transmitting device including a light source (150) having at least two separate lasers, and a unified apochromatic lens structure (148) having at least two separate lenses functioning as one structure. The lens structure (148) enables light beams (152) to a) pass therethrough onto the medium (100) with at least two different wavelengths directed to a single spot, so as to cause a localized change in chemical and/or physical properties to form an optically detectable mark (242) in the markable coating (230) and/or b) pass therethrough onto the medium (100) with at least two different wavelengths directed to a single spot, so as to cause an optically detectable mark (242) to reflect the light beams (152). The light beams (152) have radiation different from a wavelength suitable for forming the optically detectable mark (242).

    • A light collection system (200) includes a substantially elliptical first reflector (202) that defines first (204) and second (206) focal points on an axis (212). The first reflector (202) has an annular region (402) that encompasses the first focal point (204). The annular region (402) has a width W that is the distance of its projection onto the axis (212) in a direction perpendicular to the axis (212) and the width W is less than or equal to about 1/20 of a distance Df between the first (204) and second (206) focal points. A second reflector (230) has an aperture (240) through the second reflector (230) on the axis (212). The second reflector (230) is shaped and positioned to reflect electromagnetic radiation emitted from a light source (208) located at the first focal point (204) and reflected from the annular region (402) on the first reflector (202) back to the annular region (402) for reflection to a different portion of the annular region (402) and back to the aperture (240).
    • 光收集系统(200)包括基本上椭圆形的第一反射器(202),其在轴线(212)上限定第一(204)和第二(206)焦点。 第一反射器(202)具有包围第一焦点(204)的环形区域(402)。 环形区域(402)具有宽度W,该宽度W是其垂直于轴线(212)的方向上的其突起到轴线(212)上的距离,并且宽度W小于或等于距离的约1/20 第一(204)和第二(206)焦点之间的Df。 第二反射器(230)在轴线(212)上具有穿过第二反射器(230)的孔(240)。 第二反射器(230)被成形和定位成反射从位于第一焦点(204)处的光源(208)发射并从第一反射器(202)上的环形区域(402)反射的电磁辐射回到 环形区域(402),用于反射到环形区域(402)的不同部分并返回到孔口(240)。
