Filtri per il controllo del calore
da AndoverUna combinazione di specchi caldi e freddi possono essenzialmente eliminare il 99% della radiazione generata da sistemi di illuminazione ad alta potenza. Lo specchio freddo, montato ad un angolo di incidenza di 45°, trasmette gran parte del calore riflettendo la luce visibile. Lo specchio caldo, montato perpendicolarmente al fascio di luce, riflette il restante calore, mentre trasmette il 90% della luce visibile.
Caratteristiche
- Gli specchi freddi trasmettono il NIR e riflettono il visibile
- Gli specchi caldi riflettono il NIR e trasmettono il visibile
- Insieme, essi raffreddano efficacemente sistemi di illuminazione ad alta potenza

Hot Mirrors | ||
Hot mirrors are heat-reflecting filters designed to transmit visible wavelengths and reflect near-infrared heat-generating wavelengths. Andover's hot mirrors have hard, first-surface dielectric coatings that meet or exceed the humidity and abrasion specifications listed above. The coatings are deposited onto a low-expansion material such as borosilicate glass to prevent cracking or crazing from high heat applications | 775FW82 | |
Ultraviolet Cold Mirrors | ||
Ultraviolet mirrors differ slightly from the standard cold mirror in that they reflect the ultraviolet and transmit the visible and infrared. They are excellent for applications that call for separating the ultraviolet from the visible and near infrared. | 375FV86 | |

850 nm Cold Mirrors | ||
This version of the cold mirror is identical to the standard cold mirror, but with the reflection range extended to 850nm. It has excellent transmission throughout the NIR region. | 850FK84 | |
Infrared Suppressing Filters | ||
These filters extend the blocking of standard hot mirrors across the infrared range using a combination of reflection from the dielectric stack and absorption from an infrared-absorbing filter glass. Because of this absorption factor, these filters are suitable only in low-power applications with a maximum filter temperature of 100°C. | 800FB72 |
