澳大利亚Photron   
澳大利亚Photron 力于光谱仪光源的研究，开发、制造近30年，凭藉着对合金、金属界面、阴极表面技术的了解，再加上严格的制程、最新高效率真空设备以及优良材料的筛选，所以其产制的各式中空阴极管(Hollow Cathode Lamp)拥有最短暧管(Warn up)时间及最长的灯壳寿命，故质量优异，广受各界肯定。

Photron specializes in the research, development and manufacture of high quality light sources used in analytical spectroscopy.

The principals of Photron each have more than 40 years of experience both in the design of spectroscopic instruments and light sources. The design for all lamps produced are based on actual use and experience with atomic absorption, UV-visible spectrophometers and other spectroscopic instruments. Constant development of alloys, inter-metallic species and cathode surface technology ensures the analyst of the best possible line source for AAS.

Photron specializes in R&D and manufacture of high quality light sources.

Hollow Cathode Lamps with fast warm-up times and an extended shelf life guaranteed for 5 years from the date of manufacture.
Super Lamps provide a simple and efficient equivalent to EDLS with a wider range of elements and a considerable reduction in cost.
Deuterium Arc Lamps and coded lamps for some instruments allow all users of spectroscopic instruments a complete range of high quality lamps.
