AVVERTENZA

6. Note sull'azionamento dei cursori sulla parte del condensatore

Un cursore per microscopia ha due posizioni impostate. È fissato alla parte del condensatore e
utilizzato per commutare i metodi di osservazione o gli ingrandimenti modificando la posizione
impostata. La luce intensa potrebbe raggiungere il tubo oculare quando si sposta il cursore per
cambiare la posizione impostata.
Rimuovere gli occhi dai binocoli o spegnere l'illuminazione diascopica quando si aziona un cursore.
Nella microscopia a fluorescenza diascopica in particolare viene utilizzata un'illuminazione molto
intensa, pertanto i flash molto luminosi potrebbero raggiungere il tubo oculare quando si aziona il
cursore.

7. Sicurezza

fotobiologica

Questo prodotto è progettato e prodotto nel rispetto della norma di sicurezza IEC 62471 "Sicurezza
fotobiologica delle lampade e dei sistemi di lampade".
L'illuminazione vicino al piano, la luce proveniente dalla parte binoculare del tubo oculare o della
testa e la luce proveniente dalla porta della telecamera del tubo oculare trinoculare sono classificate
nel seguente gruppo di rischio. La distanza (distanza di pericolo) dal piano o dalla parte binoculare
del tubo oculare o della testa, o dall'apertura della porta della telecamera in cui la classificazione del
gruppo di rischio è equivalente al gruppo esente che non causa lesioni fotobiologiche è la seguente.

Classificazione gruppo di

rischio

Distanza di pericolo

Rischio da luce blu

Gruppo di rischio 3

36 m

Pericolo di radiazioni a infrarossi
per gli occhi

Gruppo di rischio 3

127 m

L'illuminazione nel gruppo di rischio 3 può essere pericolosa. Fare attenzione durante la regolazione
della luminosità tramite l'apposita manopola ed evitare di fissare una luce intensa per un periodo
prolungato.

•

La sorgente luminosa LED è integrata sotto il microscopio. La luce proveniente dall'obiettivo
attraversa il condensatore e illumina il campione. Non fissare direttamente la lente del
condensatore, il campione o la zona periferica del campione e non guardare nell'obiettivo.

•

Non guardare direttamente la luce proveniente dalla parte binoculare del tubo oculare o dalla
testa.

•

Non rimuovere gli oculari dalla parte binoculare quando l'illuminazione è attiva.

•

Non fissare dall'alto la luce intensa proveniente dalla porta della telecamera.

•

Quando non si collega la telecamera, coprire la porta con l'apposito coperchio fornito in dotazione.
