The K3413-09 is a hybrid detector containing an infrared-transmitting Si photodiode mounted over an InGaAs PIN photodiode, along the same optical axis. This structure delivers a wide spectral response range from 0.25 μm to nearly 1.7 μm. The built-in thermoelectric cooler maintains a constant temperature during operation, allowing precision measurement with an improved S/N ratio.
|Spectral response range||0.32 to 1.67 μm|
|Photosensitive area (1)||2.4×2.4 mm|
|Peak sensitivity wavelength (typ.) (1)||0.94 μm|
|Photosensitivity (typ.) (1)||0.45 A/W|
|Photosensitive area (2)||φ1 mm|
|Peak sensitivity wavelength (typ.) (2)||1.55 μm|
|Photosensitivity (typ.) (2)||0.55 A/W|
|Measurement condition||Typ., Ta=25 ℃, unless otherwise noted|

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. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
