This study measured the radiant power (mW), irradiance (mW/cm2) and emission spectra (mW/cm2/nm) of 22 new, or almost new, light curing units (LCUs): - Alt Lux II, BioLux Standard, Bluephase G2, Curing Light XL 3000, Demetron LC, DX Turbo LED 1200, EC450, EC500, Emitter C, Emitter D, KON-LUX, LED 3M ESPE, Led Lux II, Optilight Color, Optilight Max, Optilux 501, Poly Wireless, Radii cal, Radii p...
Introduction[N1] :One of these annoying stimuli and a major source of stress in the NICU is sound. In neonatal intensive care units, sounds with different intensities and frequencies are produced from different sources such as fan devices, intermittent alarms, ventilators, telephones, door opening and closing, and staff conversations; Studies have reported that the average noise level in the NI...
The lighting of the operating/surgical site depends on quality from overhead light source and reflection curtain. Light measurement operating table is very necessary because it generates that irradiated into cutting wound without dazzling surface so pathological conditions can be recognized must provide depth contrast anatomical relationships, to ensure this proper calibration method needed. Lo...
Rendahnya intensitas pencahayaan pada panti asuhan di Kota Makassar, yang penghuninya didominasi usia sekolah, dapat mempengaruhi ketajaman penglihatan penghuninya. Hal ini menjadi masalah, karena mengganggu fungsi dibutuhkan dalam perkembangan anak sekolah. Penelitian bertujuan untuk mengetahui hubungan antara cahaya dengan penglihatan, faktor terlibat dalamnya, serta kondisi penerangan dan pe...
Intensity of the sun be an important parameter to determine potential energy in any region. Nowdays, measurement solar intensity as a panel tracker use many variety sensors. Phototransistor is one light sensors that has greater sensitivity compared other The design system uses four phototransistor which are placed each two east and west panel. Accuracy testing calculated by comparing results on...
Background and Objectives : Efficient Illuminance, ColorTemperature (CT), Color Rendering Index (CRI) and luminance regulations are the necessary needs for designing workplaces. The aim of this study was to investigate optical components in commercial Compact Fluorescent Lamps (CFLs). Methods : In this study, 48 coil compact fluorescent lamps available at Hamadan city market with some ...
BACKGROUND Adequate light is essential for vision during direct laryngoscopy. The ISO 7376:2009 standard specifies the minimal illuminance for laryngoscopes. No studies have objectively examined the relationship between laryngoscope illumination and visual acuity during laryngoscopy. METHODS We measured the near visual performance of 50 anesthesiologists during direct laryngoscopy using near ...
PURPOSE To compare three different pupillometers (Colvard, Procyon, and Neuroptics) for determining pupil diameter at 0.04 and 0.4 lux ambient illumination. METHODS In 92 eyes of 46 healthy volunteers, pupil diameter was measured at 0.04 and 0.4 lux. After dark adaptation for 2 minutes, measurements were performed with each device by two examiners. Interobserver agreement, instrument agreemen...
