2. Photochemical radiance

The photochemical radiances at each photography modes irradiated from this instrument to the examinee’s eyes are indicated below. All the values in the following table were measured when the instrument was operating at maximum light intensity and maximum aperture.

La [mW/cm²/sr] Lb [mW/cm²/sr]

(1) Color 0.352 0.347

(2) Red Free 0.009 0.009

(3) Fluo 0.252 0.252

3. The above values are spectrally weighted radiance on the pupil of examinee’s eyes in each

wavelength. La gives the measure for eyes in which the crystalline lens has been removed (aphakes) or for eyes of infants. Lb gives this measure for eyes in which the crystalline lens is in place except for infants’. Spectrally weighted photochemical radiances La and Lb give a measure of the potential that exists for a beam of light to cause photochemical hazard to the retina.

000_L-IE-5152E_CF-1.book Page 5 Monday, July 29, 2013 10:30 AM

According to the American Conference of Governmental Industrial Hygienist (ACGIH) Threshold Limit Values for Chemical Substances and Physical Agents (1995 - 1996 edition), at photochemical radiances La and Lb of 80 [mW/cm²/sr], 3 minutes irradiation would cause the retinal exposure dose level to attain the recommended exposure limit. If the value of radiance was 40 [mW/cm²/sr], 6 minutes would be needed to reach the recommended limit. That is, the retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. Since La and Lb of this instrument are extremely low, the risk of the photochemical hazard is also very low. While no acute optical radiation hazards have been identified for this instrument, it is recommended that the intensity of light directed into the examinee’s eye be limited to the minimum level which is necessary for diagnosis. Infants, aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if the person being examined has had any exposure to the same instrument or any other ophthalmic instrument using a visible light source during the previous 24 hours. This will apply particularly if the eye has been exposed to retinal photography.

photographic images of them (in 4 modes: color, red-free, OPTION and fluorescein angiography).

The camera has the following features:

Compact size and superior operability

The controller has been designed as a single integrated unit, offering a compact size and light weight.

The system offers enhanced ease of operation, making it significantly more efficient and comfortable to

assist patients. The alignment procedure has also been improved now that the main unit can be raised and

lowered by the operation lever and the chin rest is motor driven.

Panning and tilting functions provided as standard features

Panning and tilting functions are provided as standard options.

These functions make it possible to undertake focusing and panning or tilting at the same time.

Support for photographing small pupils

The camera can photograph small pupils when the pupils have a field angle of 50° and a diameter of

5.2 mm or greater.

If it is difficult to dilate the pupil of a patient’s eye, the small pupil photography function enables

photographs to be taken of pupils with a diameter of ø4.3 mm or greater.

System optimized for digital photography

By using the Retinal imaging control software MYD (hereinafter called “control software”), the images

photographed by the CF-1 can be browsed, processed, stored, output to the DICOM storage server,

exported to DICOM files and output to an inkjet printer.

High-speed image transfer is enabled using the USB 2.0 interface. In addition, depending on whether

color, red-free, OPTION or fluorescein angiography is established as the photography mode, the lighting

system filter, flash intensity and EOS digital camera are automatically set and other steps are taken to

optimize the photography workflow.

High picture quality, high-definition diagnostic images

Diagnostic images with a high picture quality and high definition can be obtained by using an EOS digital

camera that incorporates a large, high-definition CMOS sensor.

2. Notes for Using the Instrument

Before Use

• Take a daily test image to ensure that there is no foreign matter present that can affect image readings.

• Check and clean the objective lens before taking an image, as any stains or scratches on it will appear

as white spots.

• Sudden heating of the room in cold areas will cause condensation to form on the objective lens or on

optical parts inside the instrument. In this case, wait until condensation disappears before performing

photography.

• Do not touch the lens of the main unit or the mirror of the digital camera when attaching and detaching

the digital camera from the main unit.

If any dirt, fingerprints, dust, or other foreign objects attach to the lens or mirror, you will not be able to

take a good image.

• Be sure to adjust the diopter of the viewfinder to match the diopter of the photographer’s eye. Otherwise,

focusing will not be able to be performed correctly.

After Use

• Turn OFF the power of the instrument. Place the cap over the objective lens, and place the dust cover

over the instrument.

You will not be able to take a good picture when the objective lens is dirty.

• If the EOS digital camera is removed and left unattached, dust and other foreign objects can enter the

main unit and the EOS digital camera. Always be sure to attach the caps to the respective mounts.

Cleaning and Disinfection

• Do not let the tip of a blower touch the objective lens.

• Do not wipe off or rub the objective lens when there is dust or other substances on it.

This could scratch the lens surface.

• Never wipe the objective lens with disinfecting ethanol, eyeglass lens cleaner, or cleaning paper

containing silicon.

The lens surface could be damaged or the surface may not be completely wiped off.

• Do not clean the cover of the instrument with lens cleaner. The cover of the instrument could be

damaged.

• Never use alcohol, benzine, thinner, or other solvents to clean the cover of the instrument. This could

damage the cover of the instrument.

• Never use disinfecting ethanol, glutaraldehyde or other solvents to clean the cover of the instrument,

except the forehead rest and the chin rest. This could damage the cover of the instrument.

• If the chin rest paper will not be used, be sure to disinfect the chin rest for each patient in the same

manner as for the forehead rest.
