Filtru pentru observatii astronomice – Clear Sky-v1 – 1.25inch

Descriere

Produs realizat prin tehnologia Physical Vapor Deposition (PVD) in laboratorul de acoperiri optice al Lambda Physics SRL.

Filtrul are o transmisie selectiva in domeniul spectral vizibil, prin atenuarea mai accentuata a lungimilor de unda care fac parte din poluarea luminoasa atmosferica, precum:

• Luminile stradale fluorescente și alte surse industriale (500 – 540nm);
• Sursa naturală (Airglow): Emisia aerului atmosferic cu cea mai puternica emisie la 558nm (Oxigen);
• Iluminarea “led alb – albastrui” provenita de la  autoturisme (470 – 500nm);
• Lampi cu mercur (546 si 578nm)

Spectrul de transmisie este disponibil in galeria foto a produsului.
Filtrele se livreaza montate in rama din aluminiu anodizat, fiind compatibile cu ocularele de 1.25 inch.

Product made by Physical Vapor Deposition (PVD) technology in the optical coatings laboratory of Lambda Physics SRL.

The filter has a selective transmission in the visible spectral range, by an attenuation of the wavelengths that are part of atmospheric light pollution, such as:

• Fluorescent street lights and other industrial sources (500 – 540nm);
• Natural source (Airglow): Atmospheric air emission with strongest emission at 558nm (Oxygen);
• “White – blue LED” lighting from cars (470-500nm);
• Hg lamps (546 and 578nm)

The transmission spectrum is available in the product photo gallery.
The filters are delivered mounted in an anodized aluminum frame, being compatible with 1.25 inch eyepieces.
