10. amount of ultraviolet light is used When an ultraviolet laser is shined directly into the camera and a portion of the usable picture element area of the CCD receives a significant amount of ultraviolet light that portion of the CCD alone can suffer from deterioration in sensitivity Even when there isn t a significant amount of light entering the camera but the exposure to the light continues for a long time the sensitivity can be affected So close the shutter when not actually shooting and protect the CCD from ultraviolet light as much as possible Because the CCD is replaceable when you want to replace it due to deterioration in sensitivity contact the store where you purchased the camera However you cannot replace just the CCD you will have to replace the front panel block as a unit at additional expense 32 Specifications Image sensor XCD SX910CR SX910UV SX910 b type progressive scan IT transfer CCD XCD X710CR X710 type progressive scan IT transfer CCD Number of effective pixels XCD SX910CR SX910UV SX910 Approx 1 450 000 1392 H x 1040 V XCD X710CR X710 Approx 800 000 1034 H x 779 V 4 65 um H x 4 65 um V TEEE1394 1995 400 200 100 Mbps IIDC 1394 based Digital Camera Specification Version 1 30 Compliant Image format fixed size XCD SX910CR SX910UV SX910 1280 x 960 Mono8 16 1024 x 768 Mono8 16 800 x 600 Mono8 16 640 x 480 Mono8 16 XCD X710CR X710 1024 x 768 Mono8 16 800 x 600 Mono8 1
11. considerations when using ultraviolet light involving light reflected off the camera and light shining around at random Be sure to take all necessary safety precautions when you use ultraviolet light as a light source When you switch back and forth using ultraviolet light and visible light with the same camera due to aberrations in the lens there may be some differences in the focus when you use ultraviolet light and when you use visible light On the XCD SX910UV the flange back is 17 526 mm with ultraviolet light having a wavelength of 300 nm as the default 31 Deterioration in CCD sensitivity The sensitivity of the CCD in this camera can deteriorate over time Because ultraviolet light contains higher energy compared to visible light the elements making up the CCD can suffer damage so depending on the amount of ultraviolet light energy accumulated a lowering of the sensitivity may occur The amount of radiated energy is equal to the amount of light radiated and the length of time it is radiated thus the total accumulated radiated energy is the sum total of all the radiated energy accumulated over time The total accumulated radiated energy J cm 2 Amount of radiated light W x length of time it is radiated in seconds As an example of this particular characteristic see the following Characteristic Example 1 With ultraviolet light having a wavelength of 266 nm and total accumulated radiated energ

13. ultraviolet light permeable filter If you set this filter between the camera and the subject the sensitivity to ultraviolet light relative to visible light increases and you can create a camera system more responsive to ultraviolet light There are many types of special filters available on the market You can use filters to suit the environment and the shooting conditions and using just this camera configure a camera system that has exactly the relative sensitivity characteristics you need XCD SX910CR X710CR XCD SX910UV XCD SX910 X710 Appendix On light sources This camera is sensitive to ultraviolet light in the 400 nm or less At the same time it 1s sensitive to visible and infrared light above 400 nm in wavelength So when shooting a subject illuminated only by ultraviolet light the visible light or infrared light shining on the subject or entering the camera can have an influence on the image output In order to obtain an accurate image some sort of screening equipment will be needed to deal with both the visible and the infrared light If you use ultraviolet light as a light source use light waves in the appropriate range for the camera sensitivity Depending on the amount of light wavelengths shorter than 350 nm can have an effect on the human body Be especially careful to read the Operating Instructions to obtain a full understanding of how to properly use your light source In addition there are safety

43. y of 100 J cm the sensitivity of the CCD will be reduced by about 1 As an easy guideline to calculate the duration of time which causes a 1 reduction in the sensitivity with a 226 nm ultraviolet light source Characteristic Example 1 we will introduce a simpler version of the formula used above to calculate the total amount of accumulated radiated energy Time which causes a 1 reduction in the sensitivity in years 3 17 amount of radiated light uW This formula is based on the amount of radiated light under one light source with the camera being used continuously for 24 hours a day For example with 1 5 uW of radiated light which is the high power output from one light source the number of years it would take a 1 deterioration in sensitivity to occur is 2 11 years So if the camera is used 8 hours a day then the period is three times that or 6 33 years Characteristic Example 2 With ultraviolet light having a wavelength of 196 nm and total accumulated radiated energy of 15 J cm the sensitivity of the CCD will be reduced by about 15 As an example of the decision standard you can think of a 15 reduction in sensitivity as a guideline to use to decide when to replace the CCD However even though the conditions under which you use your XCD SX910CR X710CR XCD SX910UV XCD SX910 X710 Appendix camera change for example how wide you open the lens how long the exposure time is
