TOKINA FILTER PRO IRND 1.8




Ved hjælp af den innovative Accu-ND-teknologi har udviklingsteamet hos Kenko Tokina skabt et Neutral Density-filter (ND), som meget præcist kontrollerer mængden af lys, der trænger ind i filteret, uden at påvirke farverne. Et revolutionerede filter, som stabiliserer farvetransmittansen i det synlige spektrum.

Tokina PRO IRND-filtre fås i to typer, rundt og firkantet/retangulært. Det runde PRO IRND-filter har ND-dampaflejrings-coating på begge sider af glasset, hvilket skaber et meget præcist og helt neutralt filter. Det firkantede/retangulære filter har ND-dampaflejrings-coating mellem de to glaslag, så filteret kan pudses op igen og igen, hvorved filterets levetid forlænges.

Der findes to typer fremstillingsprocesser på markedet i dag, når det gælder IRND-filtre. Den ene type skærer det infrarøde væk fra den pågældende bølgelængde, mens den anden type kontrollerer det infrarøde op til 1200nm, i stedet for at skære. Tokina PRO IRND-filtrene er i sidste kategori, hvor den infrarøde forurening undertrykkes. Selvom begge metoder kan være lige effektive, skaber den første metode ofte uønskede farveskift.

In terms of the development team at Kenko Tokina with their innovative Accu-ND Technology, creating a Neutral Density filter that precisely controls the amount of light entering the lens without affecting the color. A revolutionary filter that stabilizes the transmittance of color throughout the visible spectrum.

The Tokina PRO IRND filter is available in 2 styles, round and square/rectangular.The round PRO IRND filter has an ND vapor deposition coating on both sides of the glass creating a high precision, truly neutral filter. The square/rectangular type of filter has an ND vapor deposition coating sandwiched between two layers of glass so the filter can be re-polished again and again should it get scratched, extending the life of the filter.

There are generally two types of IRND filter manufacturing processes currently in the market today. One type cuts the near infrared from a particular wavelength and the other controls rather than cuts the infrared up to1200nm. The Tokina PRO IRND filter is of the latter category, using suppression rather than cutting to eliminate infrared pollution. Even though both methods can be equally effective, the former type of cutting is often prone to producing unwanted color shifts.

Tokina PRO IRND-filtere fås i to typer, rundt og firkantet/rektangulært. Det runde PRO IRND-filteret har ND-overflatebehandling på begge sider av glasset, noe som skaper et meget presist og helt nøytralt filter. Det firkantede/retangulære filteret har ND-overflatebehandling mellom de to glasslagene, slik at filteret kan pusses igjen og igjen, hvorav filterets levetid forlenges.

Det finnes to typer fremstillingsprosesser på markedet i dag når det gjelder IRND-filtere. Den ene typen kutter det infrarøde fra en bestemt bølgelengde, mens den andre typen kontrollerer det infrarøde opp til 1200nm i stedet for å kutte. Tokina PRO IRND-filtrene er i siste kategori, hvor den infrarøde forurensningen undertrykkes. Selv om begge metoder kan være like effektive, skaper den første metoden ofte uønskede fargeendringer.
