Nova Phase specializes in custom optics made to your exacting needs – from prototypes to full OEM production. With a proven track record of on-time deliveries of the highest quality optics, we are ready to meet your custom optics needs.

To assist you, we’ve prepared a brief write up of the common optical specifications and design considerations. Please do
not hesitate to call us for more information.

Understanding Optical Specifications

When ordering custom optics, a number of issues arise that can dramatically effect the overall performance and cost of the
final optic. In general, a more stringent specification will add additional cost to the finished piece. The goal is to determine
an optic that meets, without exceeding, the required specifications for the application. Our opticians have a combined experience of over 60 years in fabricating custom optics and can help you achieve the best price / performance ratio for your
custom optic requirement.

Nova Phase has compiled the following information to help clarify the various specifications needed when designing an
optic and their relative cost impact.

Surface Quality
The scratch-dig ratio (S-D) and the wavefront error are two prominent surface quality factors that effect optical performance.

Scratch-Dig – This parameter describes surface blemishes left after final polishing and coating (where used). Mil Spec
MIL-0-13830A is used as the industry standard for defining scratch digs.

The first number, the scratch, refers to the maximum allowable scratch width in microns (i.e. a 60-40 S-D number specifies
a maximum scratch width of 60mm). The tolerances on the scratches are defined as:

#10 scratch = 10 ± 0.5 μm
#20 scratch = 20 ± 1.0 μm
#40 scratch = 40 ± 2.0 μm
#60 scratch = 60 ± 3.0 μm
#80 scratch = 80 ± 4.0 μm

The second number, the dig, refers to pits or small craters on the surface of the optic. The dig number describes the diameter
of the digs in 1/100th of a millimeter (i.e. 60-40 refers to a dig of 0.4mm in diameter. The tolerances on the digs are
defined as:

#5 dig = 0.05 ± 0.00254 mm
#10 dig = 0.10 ± 0.00508 mm
#20 dig = 0.20 ± 0.00762 mm
#40 dig = 0.40 ± 0.01016 mm
#50 dig = 0.50 ± 0.01270 mm

Practical Examples of Scratch-Dig:

Scratch-Dig Application Relative Cost
80-50 A cosmetic standard, low cost imaging systems $
60-40 Commercial grade, non-critical applications $$
40-20 Standard scientific research applications $$$
20-10 Laser mirrors and extra-cavity optics $$$$
10-5 Intra-cavity laser optics, high power applications $$$$$$

新的阶段，擅长于风俗光学作出你的严苛需求-从原型，以充分O EM生产。一个已经验证的记录就准时送货量的最高品质光学的，我们已准备就绪，以满足您的定制光学需要。

帮助你，我们已经准备了简短的写起来的共同光学规格及设计上考虑。请勿
不要犹豫，请我们了解更多信息。

了解光学规格

最后视神经。一般来说，一个更加严格的规范，将增加额外的成本，以成品一块。目的是为了确定
一种视神经满足，而不越位，所要求的规格，其申请。我们的配镜师有一个联合的经验超过60年的捏造定制光学及可以帮助你达到最佳的价格/性能比，为您的
定制视神经的要求。

新的阶段，汇编了下列资料，以协助澄清各种规格时，需要设计一个

表面质量
划痕非开挖比例（ SD ）和波前误差是两个突出的表面质量因素的影响光学性能。

刮掉挖-这个参数描述表面不被弄脏后，留下最后的抛光及涂层（如使用） 。百万规格
百万- 0 - 13830a是用来作为行业标准来界定从头开掘。

第一个数字，从零开始，是指以最高容许从零开始宽度在微米（即60-40的SD若干具体规定
最高从零开始宽度60毫米） 。公差就被抓伤的定义是：

＃ 10从零开始= 10 ± 0.5 μ m的
＃ 20从零开始= 20 ± 1.0 μ m的
＃ 40从零开始= 40 ± 2.0 μ m的
＃ 60从零开始= 60 ± 3.0 μ m的
＃ 80从零开始= 80 ± 4.0 μ m的

第二个号码，挖掘，是指窖或小环形山上的表面光。挖若干描述直径
该开掘在1/100th一毫米（即60-40指的是一个挖的0.4毫米直径公差就开掘是
定义为：

＃ 5挖= 0.05 ± 0.00254毫米
＃ 10挖= 0.10 ± 0.00508毫米
＃ 20挖= 0.20 ± 0.00762毫米
＃ 40挖= 0.40 ± 0.01016毫米
＃ 50挖= 0.50 ± 0.01270毫米

实际例子刮掉挖：

60-40商业等级，非关键性应用元元
40-20标准科研应用元元元
