Detailed Description  Parameter  · It adopts CCFL(Cold cathode fluorescent lamp) · knob adjust the lightness continuously; · Foot Switch Control · Power144W · Pan-Blue light ,Can reduce eyes fatigue; · Product size510×180×160mm,view size300×70mm · It can view the highest blackness 4.5 negatives  · The low heat, does not have the noise, will not damage the film  · CCFL lumious tube using time is over 30000hours · Designs simply, novel, dexterous, portable  The characteristics of the Delight Industry nagative film viewer The excellent selected material:  the viewer's viewing screen and optical path material are all adopted of acrylic glass plate manufactured by japan mitsubishi liyan company.  It adopts the newest backlighting technology of natural color TFT LCD  Reducing eyes fatigus   It adopts CCFL(Cold cathode fluorescence lamp)luminous source made by Germany,its glint frequency is over 50000 times,human eyes have not been able to feel the glint,even watching in a long time eyes no longer feel fatigue.  The luminous tube life is super long,no noise and energy saving :  CCFL lumious tube use time exceeds 30000 hours,that is 20 times of common fluoresence lamp'due to use high frenquency inverter circuit theory,it doesn't has humming of traditional rectifier.The luminous tube heating is minimum,more energy saving,the power consumption is only 1/3 of traditional viewer. It is more suitable for watching Industry films  Its lightness color temperature exceeds 10000k,and adopting natural light verisimilitude design surface luminous source.The light beam transmitting is more equally and the lightness difference is less than 10%,that lets film image is more true to nature,good looking and more suitable to watch film.
