Proximity Ambient Light

Murata LT-1PA01 proximity illuminance sensor,  dimensions 3.05mm x 2.1mm x 1.1mm, an optical proximity sensors and illumination sensors.

OSRAM Opto Semiconductors Proximity Ambient Light Sensors: Osram SFH 7770 E6,OSRAM SFH 7741,Osram SFH 4059,Osram SCDQ5544Q,Microchip PIC18F46J50.
SMT Proximity and Ambient Light Sensor from Osram.

AMS AG: The Ambient Light Sensor & Proximity Detection product family provides both ambient light sensing (ALS) and proximity detection in a single device. 

Avagotech: The integrated ALS+PS module offers ambient light sensing and proximity sensing capabilities in one single device. This very small-size integrated sensor provides ease of implementation as it eliminates design efforts required for separate ALS and PS solutions.

Some new Proximity Ambient Light sensors:

TMD27723 Ambient Light Sensor from AMS, Digital ambient light sensor, proximity sensor and IR LED in an optical module 1.8v I2C

Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL6180X precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor
