此系列包含三种具有不同中心灵敏度波长的类型：220 nm、254 nm 和 275 nm。
光谱灵敏度特性半宽度 (FWHM) 在 10 nm（典型）处极窄，因此可以准确进行光度测量，同时杂散光极少。
S12742 系列可定制，以支持其他最大灵敏度波长，例如 340 nm、560 nm。
探测器：光电倍增管（Cs-Te 光阴极面）（200 至 320 nm）
光电倍增管（多碱光阴极面）（280 至 720 nm）
硅光电二极管（680 至 1100 nm）

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently.
