TH 7895M-(H)

DESCRIPTION

TH 7895M-(H) WITH UV COATING

UV coating is a proprietary organic phosphor developed in order to improve sensitivity of charge-coupled devices (CCDs) in

blue-visible and ultraviolet wavelengths. A 0.4 to 0.6 µm thick coating applied to frontside-illuminated CCD dramatically im-

proves the quantum efficiency of the device in the 120 nm to 450 nm range.

Optical properties : UV coating emits light at approximately 540 to 580 nm when excited with light of wavelengths shorter

than 450 nm. The conversion efficiency of the coating is nearly unity, which makes it an ideal ultraviolet downconverter for

silicon detectors. At wavelengths longer than 480 nm, UV coating is transparent and, thus, has no detrimental effect on the

quantum efficiency of a CCD in the visible and near-infrared portions of the spectrum.

The window is transparent down to 180 nm (quartz window).

ABSOLUTE MAXIMUM RATINGS

Same values as standard device except for :

Storage temperature .................................................................................................................................................. – 55°C to + 50°C

Operating temperature............................................................................................................................................... – 40°C to + 50°C

OPERATING RANGE

Operating range defines the limits between which the functionality is guaranteed.

Electrical operating range : same as standard TH 7895M-(H).

Thermal limits are given in image grade specification.

STORAGE

The pieces must be stored in darkness.

UV coated CCD with non sealed window must be stored in dry inert atmosphere, such as nitrogene, to prevent a UV

sensitivity decrease.

OPERATING CONDITIONS

Same values as standard devices.

ELECTROOPTCAL PERFORMANCE

Performances in visible spectrum

General measurement conditions, performance characteristics and image grade specification are the same as TH 7895M-(H)

grade ones, except for PRNU whose maximum value σ is 4.3 % (typically 2.6 %).
